Patent ID: 8416819

Claim:
A method for generating a compensated train of short temporally equidistant laser pulses, the frequency comb of which comprises equidistant individual lines whose carrier envelope offset frequency (f CEO ) is adjusted to a predetermined value, comprising the steps of: receiving an uncompensated train of short temporally equidistant laser pulses; determining a CEO signal having a frequency corresponding to the carrier envelope offset frequency (f CEO ) of individual lines in the frequency comb of the uncompensated train of short equidistant laser pulses; controlling an acousto-optical frequency shifter with a control signal derived from the CEO signal; and leading the uncompensated train of short pulses on the acousto-optical frequency shifter, so that in a first diffraction order the compensated train of temporally equidistant short laser pulses is generated in which the individual lines of the pertinent frequency comb are shifted by the frequency (f s ) of the control signal.
