摘　　要：将非水基流延成型和真空烧结技术制备的YAG/Yb:YAG/YAG平面波导陶瓷作为激光放大器的增益介质,研究其激光放大特性。种子源为1030 nm保偏光纤激光器,放大器的抽运源为940 nm半导体激光器阵列,抽运光经过耦合后从端面进入平面波导。对比了前端抽运和后端抽运的放大性能,测试了双端抽运的激光放大输出性能。在双端抽运下,当注入种子光的功率为136 W时,获得了功率为1.41 kW的激光输出,斜率效率达到41%。这是已报道的该类陶瓷平面波导达到的较高功率激光输出。A YAG/Yb:YAG/YAG ceramic planar waveguide is manufactured using tape casting combined with vacuum sintering and hot isostatic pressing, which is taken as the laser gain medium to investigate the characteristics of laser amplification. A 1030 nm polarization-maintained(PM) fiber laser is used as the seed laser and a 940-nm diode laser array is used as the pumping source of the amplifier. The pumping light is coupled with the planar waveguide from the end facets. Subsequently, the amplification performances under front-end-pumping and back-end-pumping are compared, and the amplification performances of dual-end pumping are experimentally tested. In case of dual-end pumping, when the seed laser power is 136 W, the laser output power is observed to be 1.41 kW and the slope efficiency is up to 41%. To the best of our knowledge, this is the superior output power worldwide for a laser with this type of ceramic planar waveguide.
