Abstract
The designs to generate nanosecond pulses with thin disk lasers as well as the results will be discussed. In Q-switched operation 18 mJ pulse energy at 1 kHz repetition rate with a pulse duration of 230 ns have been achieved. Cavity dumping is also demonstrated with 12 mJ pulse energy at 1 kHz and a pulse duration of 30 ns. In an amplifier set-up 37 mJ at 1 kHz with 9 ns pulse length (FWHM) have been demonstrated. The additional advantage of this set-up is the possibility to adjust both spectral and temporal shape of the output pulses and the output energy, independently. The output of the regenerative amplifier was tunable within 10 nm around 1030 nm.
