Abstract

The invention relates to a laser device comprising a laser source (1), which is configured to emit pulsed laser radiation (2) with a spectrum in the form of a frequency comb having a plurality of equidistant spectral lines, an optical modulator (3), which is configured to shift the frequency of the laser radiation (2), and a control unit (10), which is configured to control the modulator (3) by means of a control signal (6). It is the object of the present invention to demonstrate an improved way, compared to the prior art, of generating an optical frequency comb that is stabilized in terms of the CEO frequency, in which the CE phase is also adjustable. To this end, the invention proposes that the laser radiation (2) emitted by the laser source (1) is stabilized in terms of the carrier-envelope frequency. Furthermore, the invention relates to a method of generating an optical frequency comb.
