摘　　要：研究了Yb∶YAG薄片激光器中影响激光介质温度的几个因素。理论和实验均表明减薄Yb∶YAG片并增加抽运光被YAG片吸收的次数 ,是降低激光介质温度、提高激光器输出功率和效率的有效途径。用 0 .35mm厚的Yb∶YAG薄片获得 15 .9W的 1.0 3μm激光输出 ,斜率效率超过 40 %。Some factors affecting the temperature of laser crystal in Yb∶YAG thin disk lasers are studied. The theoretical and experimental results show that reducing thickness of the crystal and increasing the number of pump passes simultaneously are effective to reduce the temperature of crystal and to improve the output power and efficiency of the lasers. As a result, 15 W output power at 1.03 μm with a slope efficiency over 40% from a 0.35 mm thick Yb∶YAG disk laser is obtained.
