Method and Device for Generating Pulsed Laser Radiation

A device for generating stabilized, pulsed laser radiation, comprising

• a mode-locked laser that generates 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,
• a first high-frequency oscillator that generates a high-frequency reference signal,
• a first phase or phase frequency detector that derives a first controlled variable from the pulsed laser radiation and the reference signal by means of phase comparison,
• a continuous-wave laser that generates narrow-band continuous-wave laser radiation at a reference wavelength,
• a first control element that derives a first manipulated variable from the first controlled variable and controls the continuous-wave laser for setting the reference wavelength in accordance with the first manipulated variable,
• a superposition element that superposes the continuous-wave laser radiation and the pulsed laser radiation and derives a second controlled variable from the superposition signal, and
• a second control element that derives a second manipulated variable from the second controlled variable and controls the mode-locked laser for setting the repetition frequency in accordance with the second manipulated variable.
