摘　　要：研究了半导体激光二极管泵浦Yb:YAG薄片激光器的调谐和腔内倍频.通过在激光谐振腔内插入石英双折射滤光片,对激光中心波长进行调谐,调谐范围为1020.5nm到1034.7nm;采用折叠腔,使用Ⅰ类临界相位匹配的LBO晶体腔内倍频,室温下得到2.5W连续515nm绿光输出,1小时内绿光最大输出功率的波动小于1%.A diode-pumped tunable Yb：YAG thin disk laser was studied. Tuning wavelength range from 1020.5 nm to 1034.7 nm was obtained by using a quartz-birefringent filter set in the laser cavity. And the generation of 515 nm green laser was demonstrated by intracavity frequency doubling of type-I phasematched LBO in a fold cavity. A CW output power of 2.5 W at 515 nm was achieved. The fluctuation of green laser was less than 1% at the maximum output power in 1 hour.
