Pulse-stacking technique for enhanced performance of a solid-state laser pumped by a high-pulse-rate source

摘要

We report on a pulse-stacking technique in which a Cr,Nd:GSGG laser pumped by a high-pulse-rate (25 kH↓(z)) source is Q switched at lower pulse rates (submultiples of the pump rate) to achieve higher-output pulse energies and shorter pulse durations. For six pump pulses stacked, the output peak power increased by a factor of 10 compared with gain-switched output. # 1998 Optical Society of America OCIS codes: 140.3210, 140.5680.
