Abstract: The disclosure relates to a device for generating pulsed laser radiation, having a laser resonator which contains a laser-active medium (EDF1, EDF2), a pump light source which optically pumps the laser-active medium (EDF1, EDF2) at a pump power (P), and a mode coupling device which is intended to effect phase coupling of the modes of the laser radiation circulating in the laser resonator, so that the spectrum of the laser radiation forms a frequency comb. The disclosure also relates to a method for designing or operating such a device. The disclosure proposes that phase noise of the frequency comb, i.e. the width of spectral lines of the frequency comb, is minimized at a predetermined useful frequency by adjusting the frequency of the pump power fixed point (vfix,pump) of the frequency comb.

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.
