采用Nd：YAG晶体和Nd：YVO（4）晶体的组合，实现了声光调Q双棒激光器。为了进行比较研究，还设计了声光调Q双棒Nd：YVO（4）-Nd：YVO（4）激光器。69和75？双棒Nd：YAG-Nd：YVO（4）激光器和双棒Nd：YVO（4）-Nd：YVO（4）激光器在连续运转下分别获得了1 W的近衍射极限激光输出。在Q开关操作，500？kHz输出，64.2？W平均功率和650？73.2？kHz激光Nd：YAG-Nd：YVO（4）激光器和Nd：YVO（4）-Nd：YVO（4）激光器的平均功率分别达到10 W。对脉冲宽度、脉冲重复率、输出功率和光谱特性进行了详细的比较和讨论。
We demonstrated an acousto-optically (AO) Q-switched dual-rod laser with different gain crystals in the cavity, the combination of Nd:YAG crystal and Nd:YVO(4) crystal. An AO Q-switched dual-rod Nd:YVO(4)-Nd:YVO(4) laser was also configured for comparative investigation. A 69 and 75?W near diffraction-limited laser in CW operation was obtained for the dual-rod Nd:YAG-Nd:YVO(4) laser and dual-rod Nd:YVO(4)-Nd:YVO(4) laser, respectively. In the Q-switched operation, 500?kHz output with 64.2?W average power and 650?kHz laser with 73.2?W average power was achieved for the Nd:YAG-Nd:YVO(4) laser and Nd:YVO(4)-Nd:YVO(4) laser, respectively. The detailed comparison on the performance of pulse duration, pulse repetition rate, output power, and optical spectrum was also investigated and discussed.
