摘　　要：研究了国产Yb∶YAG陶瓷的激光输出特性.激光器采用激光二极管(LD)纵向同轴抽运Yb∶YAG陶瓷样品,样品的掺杂原子数分数为1%,一端面镀940 nm和1030 nm双增透膜,另一端面镀1030 nm增透膜,激光器在1031 nm处获得了近红外激光输出.实验中分别测试了Yb∶YAG陶瓷在不同输出透射率(T=4%,8%,10%)条件下的激光输出特性.整个实验过程中,激光器维持基横模运转.当输出透射率为10%,吸收的抽运功率为9 W时,激光器获得最大的激光输出功率为1.63 W,相应的斜率效率为23.2%.The output performance of a domestic Yb： YAG ceramic laser is studied. The laser diode-end-pumped Yb：YAG ceramic is doped with atomic fraction of 1%, with one end face of high transmission at 940 nm and 1030 nm and the other of high transmission at 1030 nm. The near infrared laser output at 1031 nm is obtained. The output performance of Yb：YAG ceramic laser under different transmissivities （4%, 8%, 10%） is experimentally tested. The maximum output power of 1.63 W is obtained with output transmissivity of 10%, absorbed pump energy of 9 W, and slope efficiency of 23.2%.
