本文提出并论证了采用不同输出耦合器的Nd：GYSGG激光器的双波长自调Q运转。在自调Q工作中，在1056.86 ~ 1060.23 nm之间发现了两条激光线，在泵浦功率为4 W时，获得了最短脉宽为2.02 μs的激光输出，最大平均输出功率为565 mW，光转换效率为14.13%。脉冲重复频率为50.2kHz，单脉冲能量为11.25 μJ。该系统非常稳定，适合于多波长脉冲的产生。
A dual-wavelength self-Q-switched operation of Nd:GYSGG laser with different output couplers is proposed and demonstrated. In self-Q-switched operation, two laser lines between 1056.86 nm and 1060.23 nm were found. Under the pump power of 4 W, the shortest pulse width of 2.02 μs was obtained with a maximum average output power of 565 mW and the optical conversion efficiency of 14.13%. The pulse repetition rate and single pulse energy were 50.2 kHz and 11.25 μJ, respectively. The system is very stable and suitable for generation of multi-wavelength pulses.
