Abstract:
1. A system for generating a shifted frequency comb having a desired carrier-envelope phase, the system comprising: a frequency comb generator to generate a frequency comb; a frequency-shifting device, in electromagnetic communication with the frequency comb generator, to receive the frequency comb from the frequency comb generator and to produce the shifted frequency comb based on (i) the frequency comb and (ii) an error signal representative of a phase difference between the shifted frequency comb and a reference signal, the reference signal being representative of the desired carrier-envelope phase; and a detector, in electromagnetic communication with the frequency-shifting device, to receive the shifted frequency comb from the frequency-shifting device, to sense the phase difference between the shifted frequency comb and the reference signal, and to provide the error signal to the frequency-shifting device in a feedback loop.
