摘要：

We report on a passively Q-switched diodepumped Nd:YAG laser including an intracavity optical parametric oscillator, that generates 120-mu J pulses with 1.6ns time duration (75 kW peak power) at 1572 nm with excellent beam quality (M-2 approximate to 1.1) and pulse amplitude fluctuation approximate to 2%. The passively Q-switched laser alone, pumped by a 200-Hz repetition rate, 80-W peak-power single diode bar, produced linearly polarized pulses of 12 ns and 460 mu J energy at 1064 nm. A different: more complex cavity setup optimizing the passive Q-switching yielded 160-mu J 2-ns signal pulses with slightly increased peak power.
