Abstract: A method for generating stabilized, pulsed laser radiation is disclosed, the method including at least the steps of generating pulsed laser radiation at a repetition frequency, wherein the spectrum of the pulsed laser radiation is a frequency comb having a number of equidistant spectral lines; deriving a first controlled variable from the pulsed laser radiation by means of phase comparison with a high-frequency reference signal; generating narrow-band continuous-wave laser radiation at a reference wavelength; setting the reference wavelength in accordance with a first manipulated variable derived from the first controlled variable; deriving a second controlled variable by means of superposition of the pulsed laser radiation and the continuous-wave laser radiation; and setting the repetition frequency in accordance with a second manipulated variable derived from the second controlled variable. A device for generating stabilized, pulsed laser radiation compatible with the method is also disclosed.
