摘要
We present a 400 W Q-switched 532 nm laser using several techniques to control the pulse duration and shape. The laser consists of two separate intracavity frequency-doubled cavities, incoherently combined to give 50 mJ total pulse energy. By extending the cavity length the pulse duration can be increased from 66 ns to 140 ns at 8 kHz with no significant power reduction. Varying the repetition rate and the triggering delay for each cavity’s Q-switch allows further adjustment of the pulse duration. The pulse shape can be controlled by adjusting this delay and attenuating the individual cavities.
