METHOD AND DEVICE FOR GENERATING RADIATION WITH STABILIZED FREQUENCY

摘要

A method for generating radiation with stabilized frequency, comprises the steps of providing laser light pulses with a repetition frequency fR, said pulses comprising a plurality of N frequency components fn with fn = n.fr + Fo, wherein fo represents an offset frequency with n = 1, ..., N, said frequency components forming a comb with first and second different frequency portions, and generating a primary light output with at least one output frequency component corresponding to the difference of frequencies of said first and second frequency portions.
