METHOD FOR OPERATING A LASER DEVICE, RESONATOR ARRANGEMENT AND USE OF A PHASE SHIFTER

摘要

A method for operating a laser device, including providing a laser pulse in a resonator so that the laser pulse circulates in the resonator, the laser pulse having a carrier wave; determining an offset frequency (f0) of the frequency comb corresponding to the laser pulse, the frequency comb having a plurality of laser modes (fm) at a distance (frep) from one another, the frequencies of which can be described by the formula: fm=m*frep+f0, m being a natural number, and varying the offset frequency (f0) by varying a geometric phase (Δφ) that is imparted to the carrier wave of the laser pulse per resonator circulation.

1. Method for operating a laser device comprising the steps of:
a) providing a laser pulse in a resonator so that said laser pulse circulates in said resonator, said laser pulse having a carrier wave, b) determining an offset frequency f0 of the frequency comb corresponding to said laser pulse, said frequency comb having a plurality of laser modes fm at a distance frep from one another, the frequencies of which can be described by the formula fm=m*frep+f0, m being a natural number, and c) varying said offset frequency f0 by varying a geometrical phase which imparts a phase circulation delay to said carrier wave of said laser pulse-per resonator circulation.
