Abstract:
1. A laser system, comprising: a laser source generating a cw output beam at an optical emission frequency; a frequency comb source to generate a frequency comb; a detection system that receives a portion of said cw beam and a portion of said frequency comb, said detection system configured to generate a beat signal representative of a frequency difference between a line of the frequency comb and the optical emission frequency of the cw output beam; a stabilizer operatively connected to said detection system to stabilize said beat signal and said cw optical emission frequency; and a frequency shifter disposed downstream from said laser source, the frequency shifter receiving a portion of said cw output beam as an optical input and a frequency shifted beat signal as an electrical input, wherein said frequency shifter generates a line narrowed and frequency shifted cw laser output, said frequency shifter being driven by a signal derived from said beat signal in a feedforward configuration.
