报道了第一台以Nd，Cr：YAG晶体为可饱和吸收体的937 nm准三能级被动调Q Nd：GGG激光器。得到了平均输出功率、重复频率和脉宽随泵浦功率的变化关系。在泵浦功率为18.3W时，获得了重复频率为35 kHz、脉宽为45 ns、平均功率为1.18W的激光输出。相应的光-光效率和斜率效率分别为6%和10%。
We demonstrate the first quasi-three-level passively Q-switched Nd:GGG laser at 937 nm using a Nd,Cr:YAG crystal as the saturable absorber. The dependences of the average output power, the repetition rate and the pulse width on the incident pump power are obtained. A maximum average output power of 1.18 W with repetition rate of 35 kHz and pulse width of 45 ns is achieved at an incident pump power of 18.3 W. The corresponding optical-to-optical and slope efficiencies are 6% and 10%, respectively.
