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1020．5 nm到1034．7 nm；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2．5 W连续515 nm绿光输出，1小时内绿光最大输出功率的波动小于1%。
Abstract
A diode-pumped tunable Yb∶YAG thin disk laser was studied. Tuning wavelength range from 1020.5 nm to 1034.7 nn 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.
