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 kHz) source is Q switched at lower pulse rates (submultiples of the pump fate) 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. (C) 1998 Optical Society of America. [References: 10]
