Abstract

Summary form only given. We present the first results which have been achieved with a diode pumped Q-switched and frequency doubled "Corona" laser as a pump source for the Ti:sapphire based laser and regenerative amplifier operating at 10-20 kHz repetition rates. The practical, single-stage, high-average-power, high-repetition rate, all-solid-state laser system demonstrated output power of 27.2 W in a gain-switched regime and 15.2 W after short pulse regenerative amplification. These are presently the highest values obtained from a single stage system and 20 kHz is a highest repetition rate obtained for millijoule-level systems.
