Abstract

Radiation from high average power intense short pulse lasers is needed for different applications in science, industry and medicine. High repetition rate laser systems based on broadband materials like Ti-Sapphire could be good candidates to meet these requirements in the near future. Pulse amplification at 10 kHz was first demonstrated almost a decade ago,1 however recent developments in the field of high average power frequency doubled DPSS lasers bring new possibilities for the increase of Ti:sapphire laser systems average output and repetition rates and new results utilizing regenerative2 or multi-pass3 architecture for the amplifiers were reported for repetition rates of 5-7-kHz. We present here the first results which have been achieved with a diode pumped Q- switched and frequency doubled “Corona” laser produced by Coherent as a pump source for Ti.sapphire based laser and regenerative amplifier operate at 10-20 kHz repetition rates.
