A pulse width adjustable 1064 nm Q-switched cavity dumped Nd:YVO laser was realized for the first time, to the best of our knowledge, by rotating an intracavity quarter-wave plate (QWP) and a Pockels cell (PC). The pulse width adjustment range was 4.8-7.8 ns with a constant output power of 3.6 W, and it reached 4.8-13.5 ns for a lower output power of 1.3 W. The pulse width was dependent mostly on the rotating angle of the QWP and PC, but independent of the gain and pulse repetition rate.
据我们所知，首次通过旋转腔内四分之一波片（QWP）和普克尔盒（PC）实现了脉宽可调的1064纳米调Q腔倒空Nd:YVO激光器。脉宽调节范围在输出功率恒定为3.6瓦时为4.8 - 7.8纳秒，在输出功率较低为1.3瓦时达到4.8 - 13.5纳秒。脉宽主要取决于QWP和PC的旋转角度，但与增益和脉冲重复率无关。
