A self-made 15 ns, 10 mJ pulsed optical parametric oscillator was used as the pump source, peaking at 756. 3 nm, with a bandwidth more than 0. 5 nm. The 75 mm long gain medium was filled with metallic Rb and 67 kPa Ar at room temperature. When the temperature of gain medium reaches 136℃, we obtain Rb laser at 780 nm, and the output energy increases with temperature.%采用自主搭建的光学参量振荡器作为泵浦源:脉宽15 ns,脉冲能量10 mJ,中心波长756.3 nm,谱宽0.5 nm;增益介质为Rb-Ar混合气体,封装于长75 mm的吸收池内,常温下Ar的含量为67 kPa,开展了出光实验.在温度为136℃时,实现了780 nm铷激光输出.
