1. A laser device comprising:
a laser source, which is configured to emit pulsed laser radiation with a spectrum in the form of a frequency comb having a plurality of equidistant spectral lines, which laser radiation emitted by the laser source is stabilized in terms of a carrier envelope frequency,
an optical modulator, which is configured to shift at least one of a phase of the pulsed laser radiation and a frequency of the pulsed laser radiation, and
a control unit, which is configured to control the optical modulator by means of a control signal, wherein the control unit is further configured to set a phase of the control signal and thus to adjust a carrier envelope phase of the pulsed laser radiation to a pre-determinable value, and wherein the control unit is further configured to increment the phase of the control signal by a predefined value from laser pulse to laser pulse to set the carrier envelope frequency of the laser radiation.
