摘要
Generally discussed herein are systems, devices, and methods for locking an optical frequency comb. A device may include comb error measurement and control circuitry to receive a beat tone and carrier envelope offset of an optical frequency comb and provide a fast and slow repetition rate control and a fast and slow carrier envelope offset control. The repetition rate controls and carrier envelope offset controls to control actuators of an optical frequency comb generator.

The fast gain circuitry 330 as illustrated is in series with a frequency-to-voltage converter 331. The fast gain circuitry 330 applies a proportional gain to the integral-lead control signal 342 and provides a fast integral-lead signal 360 to the frequency-to-voltage converter 331. The frequency-to-voltage converter 331 converts a frequency of the fast integral-lead signal 360 to a proportional voltage, sometimes referred to as a fast control signal 361. The fast control signal 361 may be the fast repetition rate control signal and/or the fast carrier envelope offset control signal mentioned in
