Greater than 100 watt average power at 0.53 um with 25 ns 2.5 kHz repetition rate pulses from a single-power oscillator

摘要

Abstract: We have generated approximately 100 watts of frequency doubled light from the output of an electro-optically Q-switched, diode-pumped Nd:YAG slab laser oscillator operating at an average power of 200 watts (2.5 kHz repetition rate, 80 mJ/pulse, 25 ns pulsewidth). The Q- switch was a compensated z-axis propagation LiNbO$-3$/ electro-optic modulator, and the frequency conversion crystal was a thin slab of KTP. In addition, Q-switched operation at an average power of approximately 250 watts with 26 ns pulsewidths has been demonstrated. !9
