摘　　要：理论设计了二极管端面抽运Nd:YAG复合陶瓷板条,制作了双浓度掺杂的Nd:YAG复合陶瓷板条。当二极管总抽运功率为18.06kW时,通过双程放大提取了7.08kW的激光功率,光光转换效率高达39.2%,单程传输的退偏振约为3.2%。实验结果表明,Nd:YAG复合陶瓷板条对提高板条激光器的输出功率和减小退偏振具有显著的效果。A Nd： YAG composite ceramic slab end-pumped with diode is designed theoretically, and a dual concentration doped Nd： YAG composite ceramic slab is fabricated. The extracted power after double-pass amplification is 7.08 kW when the total pumping power of diode is 18.06 kW, the optical-optical conversion efficiency is up to 39.2 %, and the depolarization of single-pass transmission is about 3.2 %. The experimental results show that the Nd, YAG composite ceramic slab has significant effect on enhancing the output power and reducing the depolarization of the slab laser.
