Optical frequency combs

Menlo Systems

The SmartComb from Menlo Systems is a 19'', 3U, all fiber based compact Optical Frequency Comb. This unique system allows the user to plug in the optical fiber of the laser being measured or stabilized - SmartComb does the rest.

Features include fully automated locking electronics, fully automated beat detection, and fully automated measurement and stabilization. Made for use in- and outside of optics labs.

SmartComb can also come with various output ports at different colors for applications where frequency comb light is used as seed light or for spectroscopy.

Advanced Features and Benefits

  • touch panel control
  • beat detection unit included
  • class 1 laser
  • full automation
  • internal atomic RF clock


The FC1500-250-ULN Ultra Low Noise Optical Frequency Comb combines the versatility and ease-of-use of Menlo Systems' standard fiber-based frequency comb systems with unprecedented low phase noise and extreme stability of the generated comb radiation. The all-polarization maintaining figure 9® mode locking technology together with high bandwidth actuators for both the carrier-envelope offset frequency and the repetition rate guarantees ultimate performance.

Ever increasing demands for stability and accuracy of time and frequency signals require improved oscillators and frequency references. Today's best optical clocks rely on narrowband optical transitions and use a frequency comb as clockwork.

This new Ultra Low Phase Noise Optical Frequency Comb clearly keeps pace with the new clock designs. Phase noise on the CEO beat note is below 70 mrad (integrated from 100 Hz to 2 MHz) and is even better for the beat note used to phase lock the frequency comb repetition rate to the optical reference. The modified Allan variance reaches 3 x 10-18 within 1 s, which compares to the accuracy of today's best atomic clocks.

Advanced Features and Benefits

  • owest phase noise of <100 mrad [100 Hz-2 MHz]
  • high bandwidth >300 kHz actuators for CEO and repetition rate
  • fully fiber-coupled CEO frequency generation
  • turnkey metrology system, fully automated including data evaluation software
  • designed for continuous operation
