摘　　要：搭建Tm:YAP自调Q脉冲激光器,实验中选用掺杂浓度为5 %,尺寸是3 mm × 3 mm × 15 mm的Tm:YAP晶体作为增益介质,晶体沿c轴切割。在泵浦光斑半径为200 μm,腔长为20 mm情况下,选用的曲率半径为100 mm、300 mm和500 mm的输出镜进行实验。当泵浦功率为13.3 W,输出镜曲率半径为100 mm时,输出脉宽为0.49 μs,最大单脉冲能量为158 μJ,中心波长为2044 nm。A Tm:YAP self Q-switched pulse laser is built, the gain medium is a c-cut bulk Tm:YAP crystal with the doping concentration of 5 % and the dimensions of 3 × 3 × 15 mm3. When the pump beam waist size is 200 μm, the cavity length is 20 mm and the output mirrors curvature radius of 100 mm, 300 mm and 500 mm are selected for the experiment. When the pump power is 13.3 W and the output mirror curvature radius is 100 mm, the maximum single pulse energy can be achieved to be158 μJ, the pulse width is 490 ns and the central wavelength is 2044 nm.
