Transferring the Long-Term Stability of a GPS-Disciplined OCXO to Vescent’s FFC-100 Optical Frequency Comb by Repetition Rate Locking

We demonstrate a straightforward method of locking Vescent’s fiber frequency comb (FFC-100) repetition rate to any user-supplied RF oscillator.
To demonstrate the power of this technique, we lock the FFC-100 to an SRS FS740 GPS-disciplined oven-controlled crystal oscillator (OCXO) and show that the superb long-term frequency stability of the SRS FS740 is transferred faithfully to the frequency comb modes while retaining the short-term stability characteristic of the free-running comb tooth linewidths.

Integrated f(CEO) Phase Noise of 280 mrad RMS in a SESAM-based Frequency Comb Supporting a Fractional Frequency Instability of 1.3x10^(-17) at 1 s


Vescent presents our latest generation SESAM mode-locked Er:fiber frequency combs exhibiting a dramatically reduced phase noise in the carrier-envelope offset frequency (fceo) without sacrificing on environmental ruggedness and industry-leading compactness associated with our previous generation SESAM-based frequency combs.
