报道了用Cr4+:YAG作被动调Q,重复率为100 Hz的激光二极管泵浦的准连续板条Nd:YAG激光器的性能。观察到调Q脉冲的阈值泵浦功率、脉冲宽度、输出功率和调Q效率均与泵浦脉冲的宽度有关。得到37.4 ns(FWHM)的调Q脉冲。

In this paper the performance of a Cr 4+ :YAG passively Q-switched diode laser pumped QCW slab Nd:YAG laser with a repetition rate of 100 Hz is reported. The dependence of the pumping threshold, the pulse width, the average output power as well as the energy extraction efficiency of Q-switched pulses on input pump pulsewidth was observed. A pulse width (FWHM) of 37.4 ns of the Q switched laser was obtained. The laser system operated very stably.
