Claim 8:
9. A method for generating frequency converted laser radiation, comprising the steps of:
generating 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;
passing the pump laser radiation through a non-linear medium of a singly resonant, single-frequency optical parametric oscillator, 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 oscillation requires to reach its steady state; and
coupling 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.
