Abstract
The present disclosure relates to a method and to a device () by which a train () of short laser pulses of a mode-coupled laser () is compensated with respect to the carrier envelope offset frequency of the individual lines contained in the associated frequency comb. The aim of the disclosure is to determine the carrier envelope offset frequency and to utilize said frequency to operate an acousto-optical frequency shifter (). In said shifter, the uncompensated train of temporally equidistantly short laser pulses is diffracted in a first order such that the individual lines of the frequency comb are shifted by the carrier envelope offset frequency. The resulting compensated train of short laser pulses has a frequency comb, the individual lines of which are integral multiples of the repetition frequency of the individual light pulses in the train of short laser pulses.
