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

摘要

The invention relates to a method for operating a laser device, comprising the steps: a) providing a laser pulse (110) in a resonator (1) so that the laser pulse (10) circulates in the resonator (1), the laser pulse (10) having a carrier wave (120); b) determining an offset frequency (f0) of the frequency comb corresponding to the laser pulse (110), 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 c) varying the offset frequency (f0) by varying a geometric phase (Δφ) that is impressed on the carrier wave (120) of the laser pulse (110) per resonator revolution.
