摘　　要：报道了用Ｃｒ４＋ＹＡＧ作被动调Ｑ，重复率为１００Ｈｚ的激光二极管泵浦的准连续板条ＮｄＹＡＧ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３７．４ｎｓ（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.
