摘要

A high-repetition rate master oscillator power amplifier pumped with laser diodes(LDs) is reported.An injection seeding single-frequency electro-optical Q-switched Nd∶YAG laser is used as an oscillator,and a conductively cooled Nd∶YAG zigzag slab with a bounce-pumped architecture is utilized as a power amplifier.Pulse energies of over 800 mJ at 1 064 nm and 400 mJ at 532 nm,corresponding to average powers of 200 and 100 W,respectively,are achieved with a 12.6-ns pulse width at 250 Hz.Output frequency fluctuations and single-frequency operation are further monitored.Experimental results reveal that the proposed system,which features a single-pass amplified configuration,is a promising design for spacebased applications.
