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.

Vescent – Leading Laser Manufacturer and Developer of Precision Laser and Electro-optic Technologies

Vescent is a developer and manufacturer of novel electro-optic and precision laser technologies. Vescent offers frequency-stabilized narrow linewidth diode laser systems, precision control electronics, accessory electro-optic modules, mode-locked lasers and frequency combs.

Our scientists and engineers are continuously developing cutting-edge design solutions to laser manufacturing technical challenges.  We are adding to our SLICE line of laser control electronics that includes the unique SLICE-QTC four-channel temperature controller for lasers and electro-optics and the SLICE-DHV high-bandwidth PZT controller and high-voltage amplifier.

The family of Vescent frequency comb products is growing.  The turnkey FFC-100 and Modular FFC-CM series is now joined by the capability to lock optical frequency ƒopt to visible and near infrared (NIR) wavelength comb teeth from 650 to 1600 nm and beyond.  Through non-linear frequency conversion techniques, we have generated lockable comb teeth down to 650 nm.
