Classification: CPC G  H | IPC G  H

Claim 0:
1. A laser device comprising:
a pump laser source configured to generate pump laser radiation with a spectrum containing a plurality of equidistant spectral lines, the spectrum being either an optical frequency comb or a superposition of two or more different optical frequency combs or a superposition of a continuous wave laser radiation at one or more frequencies with one or more optical frequency combs;
a singly resonant, single frequency optical parametric oscillator comprising a non-linear medium located in an optical cavity, with the pump laser radiation passing through the non-linear medium, wherein the optical cavity is configured to be resonant at only a single cavity mode, wherein the pump laser radiation is continuous wave or pulsed, wherein the pulse duration in the latter case is longer than the time the optical parametric oscillator requires to reach its steady state; and
an arrangement of one or more optical components configured to couple out the non resonant idler and/or signal laser radiation from the optical parametric oscillator as usable frequency converted laser radiation, the spectrum of which being a frequency converted replica of the spectrum of the pump laser radiation.
