1)Phase lock to optical reference
2)Limited by resolution bandwidth of analyzer
The FC1500-250-ULN Ultra Low Noise Optical Frequency Comb combines the versatility and ease-of-use of our standard fiber-based frequency comb systems with unprecedented low phase noise and extreme stability of the generated comb radiation. Our 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 100 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.
The modular system architecture allows for easy additions of more functionality. Under the OPTIONS tab you will find the multiple extensions that can be combined with the FC1500-250-ULN.
