摘　　要：针对陶瓷晶体1319nm的谱线设计了适合的谐振腔腔镜膜系参量,采用激光二极管列阵侧向抽运掺杂1.1at%、Φ3×50mm的Nd∶YAG陶瓷,利用色散棱镜及KTP晶体Ⅱ类匹配腔内倍频,研制了一台660nm单一波长输出的高重频Nd∶YAG陶瓷红光激光器.根据陶瓷晶体的热透镜焦距设计了谐振腔的各个参量,在重复频率为1000Hz、单脉冲抽运能量约144mJ时,获得了3.9mJ的660nm脉冲激光输出,总的光-光转换效率为2.71%.为进一步研究大功率、高效率的陶瓷红光激光器奠定了基础.Using dispersing prism and KTP crystal typeⅡphase matching for intracavity frequency-doubling,the Nd∶YAG ceramic laser at the wavelength of 660 nm is studied.Suitable film parameters of resonant cavity reflectors are designed according to 1 319 nm line of Nd∶YAG ceramic,side-pumped Nd∶YAG ceramic crystal with 1.1at% Nd doping and dimensions of Φ3×50 mm.Cavity parameters are designed based on the ceramic thermal focal length.Under repetition rate of 1 000 Hz and single pulse pumped energy of 144 mJ,the output energy of 3.9 mJ at 660 nm is obtained.The optic-optic efficiency is 2.71%.The results form the basis for the further development of the high power high efficiency ceramic red laser.
