Thorlabs' External Cavity (ECL) Single-Frequency Laser Diodes deliver a narrow linewidth (50 kHz typical), single-frequency output with up to 40 mW of output power. Each external cavity, semiconductor laser is housed in a compact, 14-pin butterfly package, enabling compatibility with any standard 14-pin laser diode mount (Item # LM14S2). The single-frequency laser contains an integrated thermoelectric cooler (TEC), thermistor, and optical isolator with a single mode or polarization-maintaining output fiber with an FC/APC connector. These lasers do not have built-in monitor photodiodes and must be operated in constant current mode. For constant power mode operation, please see our TO-can, pigtailed, and butterfly laser diode offerings in the selection guide to the right for options with monitor photodiodes.
These ECL lasers are compatible with Thorlabs' line of laser diode drivers and temperature controllers. To achieve the narrowest possible linewidth, we recommend using a driver with low drive current noise, such as our LDC series of drivers.
While the SCLs are designed to provide high-power, single-frequency operation over a range of operating currents and temperatures, there are certain combinations where these lasers exhibit multimode operation. Proper temperature control and current tuning is needed to ensure single-frequency operation. To assist the user in selecting the appropriate operating conditions, a datasheet, which provides the operating characteristics and single-frequency regimes of that particular laser, is provided with each unit. For additional single frequency laser options, see our line of Distributed Bragg Reflector (DBR) lasers.
We recommend cleaning the fiber connector before each use if there is any chance that dust or other contaminants may have deposited on the surface. The laser intensity at the center of the fiber tip can be very high and may burn the tip of the fiber if contaminants are present. While the connectors on these pigtailed laser diodes are cleaned and capped before shipping, we cannot guarantee that they will remain free of contamination after they are removed from the package. For all of these pigtailed laser diodes, the laser must be off when connecting or disconnecting the device from other fibers, particularly when the power level is above 10 mW.

Figure 1: ECL Lasers have a Grating Outside of the Gain Chip
A wide variety of applications require tunable single-frequency operation of a laser system. In the world of diode lasers, there are currently four main configurations to obtain a single-frequency output: external cavity laser (ECL), distributed feedback (DFB), volume holographic grating (VHG), and distributed Bragg reflector (DBR). All four are capable of single-frequency output through the utilization of grating feedback. However, each type of laser uses a different grating feedback configuration, which influences performance characteristics such as output power, tuning range, and side mode suppression ratio (SMSR). We discuss below some of the main differences between these four types of single-frequency diode lasers.
External Cavity Laser
The External Cavity Laser (ECL) is a versatile configuration that is compatible with most standard free space diode lasers. This means that the ECL can be used at a variety of wavelengths, dependent upon the internal laser diode gain element. A lens collimates the output of the diode, which is then incident upon a grating (see Figure 1). The grating provides optical feedback and is used to select the stabilized output wavelength. With proper optical design, the external cavity allows only a single longitudinal mode to lase, providing single-frequency laser output with high side mode suppression ratio (SMSR > 45 dB).
One of the main advantages of the ECL is that the relatively long cavity provides extremely narrow linewidths (<1 MHz). Additionally, since it can incorporate a variety of laser diodes, it remains one of the few configurations that can provide narrow linewidth emission at blue or red wavelengths. The ECL can have a large tuning range (>100 nm) but is often prone to mode hops, which are very dependent on the ECL's mechanical design as well as the quality of the antireflection (AR) coating on the laser diode.

Figure 2: DFB Lasers Have a Bragg Reflector Along the Length of the Active Gain Medium
Distributed Feedback Laser
The Distributed Feedback (DFB) Laser (available in NIR and MIR) incorporates the grating within the laser diode structure itself (see Figure 2). This corrugated periodic structure coupled closely to the active region acts as a Bragg reflector, selecting a single longitudinal mode as the lasing mode. If the active region has enough gain at frequencies near the Bragg frequency, an end reflector is unnecessary, relying instead upon the Bragg reflector for all optical feedback and mode selection. Due to this “built-in” selection, a DFB can achieve single-frequency operation over broad temperature and current ranges. To aid in mode selection and improve manufacturing yield, DFB lasers often utilize a phase shift section within the diode structure as well.
The lasing wavelength for a DFB is approximately equal to the Bragg wavelength:
where λ is the wavelength, neff is the effective refractive index, and Λ is the grating period. By changing the effective index, the lasing wavelength can be tuned. This is accomplished through temperature and current tuning of the DFB.
The DFB has a relatively narrow tuning range: about 2 nm at 850 nm, about 4 nm at 1550 nm, or at least 1 cm-1 in the mid-IR (4.00 - 11.00 µm). However, over this tuning range, the DFB can achieve single-frequency operation, which means that this is a continuous tuning range without mode hops. Because of this feature, DFBs have become a popular and majority choice for real-world applications such as telecom and sensors. Since the cavity length of a DFB is rather short, the linewidths are typically in the 1 MHz to 10 MHz range. Additionally, the close coupling between the grating structure and the active region results in lower maximum output power compared to ECL and DBR lasers.

Figure 3: VHG Lasers have a Volume Holographic Grating Outside of the Active Gain Medium
Volume-Holographic-Grating-Stabilized Laser
A Volume-Holographic-Grating-(VHG)-Stabilized Laser also uses a Bragg reflector, but in this case a transmission grating is placed in front of the laser diode output (see Figure 3). Since the grating is not part of the laser diode structure, it can be thermally decoupled from the laser diode, improving the wavelength stability of the device. The grating typically consists of a piece of photorefractive material (typically glass) which has a periodic variation in the index of refraction. Only the wavelength of light that satisfies the Bragg condition for the grating is reflected back into the laser cavity, which results in a laser with extremely wavelength-stable emission. A VHG-Stabilized laser can produce output with a similar linewidth to a DFB laser at higher powers that is wavelength-locked over a wide range of currents and temperatures.
Click to Enlarge
Figure 4: DBR Lasers have a Bragg Reflector Outside of the Active Gain Medium
Distributed Bragg Reflector Laser
Similar to DFBs, Distributed Bragg Reflector (DBR) lasers incorporate an internal grating structure. However, whereas DFB lasers incorporate the grating structure continuously along the active region (gain region), DBR lasers place the grating structure(s) outside this region (see Figure 4). In general a DBR can incorporate various regions not typically found in a DFB that yield greater control and tuning range. For instance, a multiple-electrode DBR laser can include a phase-controlled region that allows the user to independently tune the phase apart from the grating period and laser diode current. When utilized together, the DBR can provide single-frequency operation over a broad tuning range. For example, high end sample-grating DBR lasers can have a tuning range as large as 30 - 40 nm. Unlike the DFB, the output is not mode hop free; hence, careful control of all inputs and temperature must be maintained.
In contrast to the complicated control structure for the multiple-electrode DBR, a simplified version of the DBR is engineered with just one electrode. This single-electrode DBR eliminates the complications of grating and phase control at the cost of tuning range. For this architecture type, the tuning range is similar to a DFB laser but will mode hop as a function of the applied current and temperature. Despite the disadvantage of mode hops, the single-electrode DBR does provide some advantages over its DFB cousin, namely higher output power because the grating is not continuous along the length of the device. Both DBR and DFB lasers have similar laser linewidths. Currently, Thorlabs offers only single-electrode DBR lasers.
Conclusion
ECL, DFB, VHG, and DBR laser diodes provide single-frequency operation over their designed tuning range. The ECL can be designed for a larger selection of wavelengths than either the DFB or DBR. While prone to mode hops, it also provides the narrowest linewidth (<1 MHz) of the three choices. In appropriately designed instruments, ECLs can also provide extremely broad tuning ranges (>100 nm).
The DFB laser is the most stable single-frequency, tunable laser of the four. It can provide mode-hop-free performance over its entire tuning range (<5 nm), making it one of the most popular forms of single-frequency laser for much of industry. It has the lowest output power due to inherent properties of the continuous grating feedback structure.
The VHG laser provides the most stable wavelength performance over a range of temperatures and currents and can provide higher powers than are typical in DFB lasers. This stability makes it excellent for use in OEM applications.
The single-electrode DBR laser provides similar linewidth and tuning range as the DFB (<5 nm). However, the single-electrode DBR will have periodic mode hops in its tuning curve.
Laser Safety and Classification
Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. The eye is susceptible to injury, even from very low levels of laser light. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina.
Safe Practices and Light Safety Accessories
- Thorlabs recommends the use of safety eyewear whenever working with laser beams with non-negligible powers (i.e., > Class 1) since metallic tools such as screwdrivers can accidentally redirect a beam.
- Laser goggles designed for specific wavelengths should be clearly available near laser setups to protect the wearer from unintentional laser reflections.
- Goggles are marked with the wavelength range over which protection is afforded and the minimum optical density within that range.
- Laser Safety Curtains and Laser Safety Fabric shield other parts of the lab from high energy lasers.
- Blackout Materials can prevent direct or reflected light from leaving the experimental setup area.
- Thorlabs' Enclosure Systems can be used to contain optical setups to isolate or minimize laser hazards.
- A fiber-pigtailed laser should always be turned off before connecting it to or disconnecting it from another fiber, especially when the laser is at power levels above 10 mW.
- All beams should be terminated at the edge of the table, and laboratory doors should be closed whenever a laser is in use.
- Do not place laser beams at eye level.
- Carry out experiments on an optical table such that all laser beams travel horizontally.
- Remove unnecessary reflective items such as reflective jewelry (e.g., rings, watches, etc.) while working near the beam path.
- Be aware that lenses and other optical devices may reflect a portion of the incident beam from the front or rear surface.
- Operate a laser at the minimum power necessary for any operation.
- If possible, reduce the output power of a laser during alignment procedures.
- Use beam shutters and filters to reduce the beam power.
- Post appropriate warning signs or labels near laser setups or rooms.
- Use a laser sign with a lightbox if operating Class 3R or 4 lasers (i.e., lasers requiring the use of a safety interlock).
- Do not use Laser Viewing Cards in place of a proper Beam Trap.
Laser Classification
Lasers are categorized into different classes according to their ability to cause eye and other damage. The International Electrotechnical Commission (IEC) is a global organization that prepares and publishes international standards for all electrical, electronic, and related technologies. The IEC document 60825-1 outlines the safety of laser products. A description of each class of laser is given below:
Class | Description | Warning Label |
---|---|---|
1 | This class of laser is safe under all conditions of normal use, including use with optical instruments for intrabeam viewing. Lasers in this class do not emit radiation at levels that may cause injury during normal operation, and therefore the maximum permissible exposure (MPE) cannot be exceeded. Class 1 lasers can also include enclosed, high-power lasers where exposure to the radiation is not possible without opening or shutting down the laser. | |
1M | Class 1M lasers are safe except when used in conjunction with optical components such as telescopes and microscopes. Lasers belonging to this class emit large-diameter or divergent beams, and the MPE cannot normally be exceeded unless focusing or imaging optics are used to narrow the beam. However, if the beam is refocused, the hazard may be increased and the class may be changed accordingly. | |
2 | Class 2 lasers, which are limited to 1 mW of visible continuous-wave radiation, are safe because the blink reflex will limit the exposure in the eye to 0.25 seconds. This category only applies to visible radiation (400 - 700 nm). | |
2M | Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. This laser class also applies to larger-diameter or diverging laser beams. | |
3R | Lasers in this class are considered safe as long as they are handled with restricted beam viewing. The MPE can be exceeded with this class of laser, however, this presents a low risk level to injury. Visible, continuous-wave lasers are limited to 5 mW of output power in this class. | |
3B | Class 3B lasers are hazardous to the eye if exposed directly. However, diffuse reflections are not harmful. Safe handling of devices in this class includes wearing protective eyewear where direct viewing of the laser beam may occur. In addition, laser safety signs lightboxes should be used with lasers that require a safety interlock so that the laser cannot be used without the safety light turning on. Class-3B lasers must be equipped with a key switch and a safety interlock. | |
4 | This class of laser may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces. Great care must be taken when handling these lasers. They also represent a fire risk, because they may ignite combustible material. Class 4 lasers must be equipped with a key switch and a safety interlock. | |
All class 2 lasers (and higher) must display, in addition to the corresponding sign above, this triangular warning sign |
Laser Diode and Laser Diode Pigtail Warranty
When operated within their specifications, laser diodes have extremely long lifetimes. However most failures occur from mishandling or operating the lasers beyond their maximum ratings. Laser Diodes are among the most static sensitive devices currently made. Since Thorlabs does not receive any warranty credit from our laser manufacturers we cannot guarantee the lasers after their sealed package has been open. Thorlabs will be happy to extend a full refund or credit for any lasers returned in their original sealed package.
Handling and Storage Precautions
Because of their extreme susceptibility to damage from electrostatic discharge (ESD), care should be taken whenever handling and operating laser diodes:
- Wrist Straps: Use grounded anti-static wrist straps whenever handling diodes.
- Anti-static Mats: Always work on grounded anti-static mats.
- Storing Lasers: When not in use, short the leads of the laser together to protect against ESD damage.
Operating and Safety Precautions
Use an appropriate driver, laser diodes require precise control of operating current and voltage to avoid overdriving the lasers. In addition, the laser driver should provide protection against power supply transients. Select a laser driver appropriate for your application. Do not use a voltage supply with a current limiting resistor since it does not provide sufficient regulation to protect the laser.
- Power Meters: When setting up and calibrating a laser with its driver, use a NIST-traceable power meter to precisely measure the laser output. It is usually safest to measure the laser output directly before placing the laser in an optical system. If this is not possible, be sure to take all optical losses (transmissive, aperture stopping, etc.) into consideration when determining the total output of the laser.
- Reflections: Flat surfaces in the optical system in front of a laser diode can cause some of the laser energy to reflect back onto the laser’s monitor photodiode giving an erroneously high photodiode current. If optical components are moved within the system and energy is no longer reflected onto the monitor photodiode, a constant power feedback loop will sense the drop in photodiode current and try to compensate by increasing the laser drive current and possibly overdriving the laser. Back reflections can also cause other malfunctions or damage to laser diodes. To avoid this, be sure that all surfaces are angled 5-10° and when necessary, use optical isolators to attenuate direct feedback into the laser.
- Thermal Management: Laser diode lifetime is inversely proportional to operating temperature. We strongly recommend the use of active temperature control in order to prevent damage and/or reduced lifetime. For assistance in picking a suitable temperature controller for your application please contact Tech Support. In addition, always mount the laser in a suitable heat sink to remove excess heat from the laser package.
- Voltage and Current Overdrive: Be careful not to exceed the maximum voltage and currents even momentarily. Also, reverse voltages as little as 3 V can damage a laser diode.
- ESD Sensitive Device: Even when a laser is operating it is susceptible to ESD damage. This is particularly aggravated by using long interface cables between the laser and its driver due to the inductance that the cable presents. Avoid exposing the laser or its mounting apparatus to ESDs at all times.
- ON/OFF and Power Supply Coupled Transients: Because of their fast response times, laser diodes can be easily damaged by transients less than 1 µs. High current devices such as soldering irons, vacuum pumps, fluorescent lamps, etc., can cause large momentary transients; use surge-protected outlets.
If you have any questions regarding laser diodes, please call your local Thorlabs Technical Support office for assistance.

Recently we bought your SFL1550P with beam collimator. I wonder you have the beam profile from the collimator output measured or expected?
Look forward to hearing from you soon. YLohia
 (posted 2020-10-26 02:30:12.0) Hello, thank you for contacting Thorlabs. Which collimator did you purchase with this laser? Please note that the laser is single-mode PM pigtailed, so the fiber acts as a spatial filter producing nearly M^2 = 1 beam quality. Demian Biasetti
 (posted 2019-10-24 04:31:41.95) Dear Thorlabs, we (Max Born Insitute, Germany) have recentely acquired a SFL 1550P Polarization mantaining laser diode but I can not find at any place which is the polariy that a must put in the LDC205C (Thorlabs) current controller (AG or CG). In the manual of Laser Diode Mount for 14-Pin Butterfy, where I inserted the Type I pin configiration card there is also no information about this. Another question is what does the "range" (in mA) of the single mode operation table, means. For different temperatures correspond different current and a ranges for single mode operation. Are the different current values the centers of their corresponding range (that appear in the next column of the table) to operate in single mode? in that case, I must tune the wavelenght. It is better that I do it just by changing the current an follow the linear dependence? Thank you. YLohia
 (posted 2019-10-28 12:06:02.0) Hello, thank you for contacting Thorlabs. The grounding should be set to AG as shown in the "Pin Diagrams" tab of the LM14S2 mount that is intended to be used with this diode: https://www.thorlabs.com/images/TabImages/LM14S2_type1_D1-600.gif. The "Current" column in the serialized SFL specsheet is the centerpoint of the range and then the single mode range is +/- (Range/2). Supriyo Babul

 (posted 2019-06-11 14:32:31.68) How is this laser different from the DBR lasers (which look the same) in your product portfolio? Does the fiber pigtail contain a Bragg grating, which provides the feedback making it an external cavity laser? Or is the Bragg reflector inside the butterfly package, but not on the same chip as in DBR lasers? YLohia
 (posted 2019-06-12 04:24:05.0) Hello, thank you for contacting Thorlabs. The DBR lasers have a Bragg reflector coated directly onto the gain chip, whereas the SFL series uses a separate grating mounted within the butterfly package (separated from the gain chip). We are currently in the process of releasing our Ultra Low Noise laser which will use a fiber-bragg grating to create single-frequency operation at 1550 nm. If you want more information about that, please feel free to reach us at techsupport@thorlabs.com. Xiaoguang Sun

I am looking for a Laser Diode at 1550nm. I have to operate it in CW mode without any modulation (I will use external modulation). However I need extremely narrow line-width as I intend to use in interferometry application for Quantum Key Distribution. I don't require wavelength tunability. Will SFL1550S be a good fit there and you suggest a better laser diode from Thorlabs. I am not interested in high optical power.
Sincerely,

 (posted 2018-09-17 10:29:37.0) Dear Atul, thank you for contacting Thorlabs. The SFL1550S will be the best fit as a single laser diode that we currently offer. We do, however, also sell the TLX1 benchtop source which is a tunable laser that covers the 1528 - 1566nm range. The typical linewidth here is 10kHz. xhyang

 (posted 2018-05-02 08:44:40.0) Hello, thank you for contacting Thorlabs. Unfortunately, we do not have this type of reliability data outside of what is given in the manual. The stability mostly depends on the mounting and drive conditions and is generally a system-level spec. Wavelength will drift with current and, to a greater extent, with the temperature. The tuning coefficients are given in the manual. The achievable linewidth will also depend on the noise of the current source. The system should be isolated from temperature changes, vibrations, etc. for optimal performance. Timohodik

Could you please provide information on lifetime in hours for
SFL1550P and CLD1015? In the case of by-the-book operation, of course.
Sincerely yours,
Timophey YLohia
 (posted 2018-02-26 09:10:42.0) Hello Timophey, thank you for contacting Thorlabs. While we have not performed any rigorous lifetime testing on the fully packaged laser SFL1550P, the component InP laser chip is very robust and advanced aging studies have estimated the chip lifetime at tens of years of continuous use before failure or degradation under normal operating conditions. In addition, we have had hundreds of units of SFL1550P in the field over the past several years without signs of failure or a high rates of return. Long-term performance may depend on environmental conditions. Unfortunately, we currently do not have the lifetime information/testing for CLD1015. We do, however, anticipate a high durability with this unit due to the very low percentage of RMAs processed since the release of this item in 2012. bsvikram
 (posted 2017-05-23 01:10:11.363) Hi, We wanted to know the highest frequency at which SFL1550S can be current modulated and whether this can be done with CLD 1015 mount. We would like to modulate the current at least at few MHz. nbayconich
 (posted 2017-06-16 08:13:21.0) Thank you for contacting Thorlabs. The SFL1550S ECL laser diode can be directly modulated up to 10 Mhz but the CLD1015 can only directly modulate a butterfly laser diode package up to 250Khz at 3 dB. Modulating at high frequencies can change the frequency spectrum of the diode but a few Mhz should not change the spectrum.
Another way to modulate the SFL1550S ECL is to use an external modulator. A Techsupport representative will contact you directly with more information. kkmion

I would like to use the SFL1150P diode laser in a pulsed mode with an appropriate driver. The driver I would use is capable to modulate the laser current up to 50MHz. My idea is to modulate the laser current between just below the laser threshold and at some current above the threshold, hence I want to create pulses in this way. The pulse width is supposed to be 100-200 ns. What is the response of your laser to such driving ?

 (posted 2013-08-09 07:57:00.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. We specify the noise and ripple of the CLD1015 with 30µA without noise reduction filter and 15µA with noise reduction filter (10Hz to 10MHz, RMS). A better solution for low noise applications would be an LDC2xxC, which can be found here: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=10. The LDC205C, for example, delivers 500mA laser current and the noise without ripple is <3µA (10Hz to 10MHz, RMS) and the ripple is <2µA (50/60Hz, RMS). I will contact you with more detailed information. |
