Micro-joule cavity-dumped wavelength-tunable semiconductor disk laser

We report on cavity-dumping of a semiconductor disk laser as a method to generate energetic wavelength-tunable nanosecond pulses with repetition rates ranging from 0.1 to 4MHz. Experimentally, emission of 24ns pulses with peak output power of 41W in a single beam output (and of 30ns with peak power of 57W in a combined beam output) with wavelength tuning from 1045–1080nm was obtained
