Abstract
The invention relates to a laser device, comprising a radiation source (1) that emits radiation having a spectrum in the form of a frequency comb having a plurality of equidistant spectral lines, and a difference frequency generator (5) that converts the radiation in such a manner that the spectrum of the converted radiation once again has the form of a frequency comb, whereby the frequencies of the spectral lines in the spectrum of the converted radiation are harmonics of a base frequency. The invention proposes that a frequency multiplier (6) follows the difference frequency generator (5) in the course of the radiation.
