Frequency comb technology makes direct measurement of absolute, SI-referenced optical frequencies possible. Menlo Systems' FC1000-250 Optical Frequency Comb is a flexible, fiber-based, femtosecond frequency comb system. The system is capable of providing a source for frequency metrology in both the visible and the near-IR regions (520 - 1040 nm) simultaneously. The laser operation relies on Menlo Systems' figure 9® mode locking technology, which ensures excellent stability and continuous performance.
The system features simple operation, as the femtosecond laser is ready to use at the press of a single button, and automatic phase lock loops ensure easy stabilization to either an RF or an optical reference. Due to the mature system design with several combined actuators, users enjoy long-term operation with no adjustment necessary over a period of weeks. A wide range of optional features enables this versatile system to be tailored to customer-specific solutions; see the Specs tab for details.

Optional Packages
EOM-Phase Electro-Optic Phase Modulator
Integrated into the laser cavity; allows high-performance phase locking to an optical reference using a high bandwidth repetition rate actuator. With this EOM option, sub-Hz line widths can be achieved.
FPC 1000 Fabry-Perot Cavity for Mode Filtering
Increases the fundamental mode spacing to a user-defined frequency in the 2 to 25 GHz range. The Fabry-Perot cavity is fiber coupled and temperature stabilized.
Orange PULSE-YDFA Ytterbium-Doped Fiber Amplifer
All polarization-maintaining (PM) amplifier delivers intense pulses at 1040 ± 10 nm. Available with single-clad fiber, which yields >1 W of power over a >15 nm spectral range, or with double-clad fiber, which yields >10 W of power over a >10 nm spectral range.
M-520 High Power Measuring Port, 520 nm
Output port provides stabilized comb light with peak power at 520 nm. Contains an amplifier and subsequent frequency conversion, delivering ≥250 mW average power in a 3 nm window centered on 520 nm. The output is free space.
BDU Beat Detection Unit
Used for generating a beat with a CW laser at a user-defined wavelength. Available in fiber-coupled or free-space versions.
LLE-SYNCHRO Laser Locking Electronics
Allows a CW laser to be locked to the stabilized frequency comb. Requires the BDU beat detection unit for generating the beat. Requires the CW laser to be tunable.
Microwave Ultrastable RF Output
Ultrastable RF output in the 1 MHz to 10 GHz range. Utilizes a fast photodetector and a frequency divider where needed.
Yb-TOD-Compressor Compression Unit
External compressor for pulse lengths down to 150 fs. Compensates for second- and third-order dispersion.
GPS GPS-Based 10 MHz Frequency Reference
Provides the RF reference input signal for the frequency comb, combining the superior short-term stability of an ultrastable quartz oscillator with the long-term accuracy of the GPS.
WLM-NIR Integrated Wavelength Meter
Integrated wavelength meter with 100 MHz accuracy for 900 - 1700 nm.
WLM-VIS Integrated Wavelength Meter
Integrated Wavelength Meter with 100 MHz accuracy for 500 - 1100 nm.
