Using an all passive approach, synchronized Q-switching of two Nd:YAG lasers, at 946 nm and 1064 nm, is reported. Two laser crystals are used to avoid gain competition, and stable operation is reported for the first time. The pulse trains are synchronized over a wide range of pump powers and a relative timing jitter of 36 ns is achieved. A minimum delay of 64 ns is observed between the two laser pulses, and by making the 946 nm pulse relatively long, a 79% temporal overlap is obtained when compared to the zero-delay scenario.
据报道，采用全被动方法实现了两台波长分别为946纳米和1064纳米的Nd:YAG激光器的同步调Q。使用了两块激光晶体以避免增益竞争，并且首次报道了稳定运行情况。在很宽的泵浦功率范围内实现了脉冲序列的同步，相对定时抖动为36纳秒。观察到两个激光脉冲之间的最小延迟为64纳秒，通过使946纳米的脉冲相对较长，与零延迟情况相比，时间重叠率达到了79%。
