A system for optical comb carrier envelope offset frequency control includes a mode-locked oscillator. The mode-locked oscillator produces an output beam using an input beam and one or more control signals. The output beam includes a controlled carrier envelope offset frequency. A beat note generator produces a beat note signal using a portion of the output beam. A control signal generator produces the one or more control signals to set the beat note signal by modulating the intensity of the input beam within the mode locked oscillator. Modulating the intensity comprises using a Mach-Zehnder intensity modulator or using an intensity modulated external laser to affect a gain medium within the mode-locked laser.

Optical comb carrier envelope-offset frequency control using intensity modulation

A system for optical comb carrier envelope offset frequency control includes a mode-locked laser and a frequency shifter. The mode-locked laser produces a laser output. The frequency shifter shifts the laser output to produce a frequency shifted laser output based at least in part on one or more control signals. The frequency shifted laser output has a controlled carrier envelope offset frequency. The frequency shifter includes a first polarization converter, a rotating half-wave plate, and a second polarization converter.
