We present a combined actively and passively Q-switched single-frequency laser that uses a codoped Cr4+,Nd3+:YAG crystal and an acousto-optic Q switch. At a maximum of 8.6 W absorbed pump power of fiber-coupled laser-diode arrays, the laser produces pulses of 1036 mW average power with a pulse duration of 8.31 ns at a repetition rate of 7.10 kHz. The output is a stable single longitudinal mode with a linewidth of 530 MHz and an interpulse timing jitter of 0.40 micros. We compare the laser with and without the Cr4+ as well as with and without an active Q switch.
我们展示了一种组合式主动和被动调Q单频激光器，它使用共掺杂的Cr4+、Nd3+：YAG晶体和一个声光Q开关。在光纤耦合激光二极管阵列的吸收泵浦功率最大为8.6 W时，该激光器以7.10 kHz的重复频率产生平均功率为1036 mW、脉冲持续时间为8.31 ns的脉冲。输出为稳定的单纵模，线宽为530 MHz，脉冲间定时抖动为0.40微秒。我们比较了有无Cr4+以及有无主动Q开关时的激光器性能。
