Abstract

A planar waveguide laser operating in a negative branch unstable resonator is Q-switched by an acoustooptic modulator in a new configuration, providing effective, high-speed switching. The laser using a 200-µm Nd:YAG core, face pumped by 10 laser diode bars, has produced 100-W output in a good beam quality at 100-kHz pulse rate, and 4.5 mJ at lower frequency with 15-ns pulse duration. © 2007 IEEE.
