摘要
报道了一种LD端面抽运Nd:YAG陶瓷、KTP腔内倍频的全固态连续波绿光激光器.当抽运功率为21.6W时,1064nm基频输出达到11.3W,光—光转换效率为52.3%.采用Ⅱ类切割的KTP晶体作为腔内倍频介质,在直腔结构下获得了最大功率为1.86W的532nm绿光输出,光—光转换效率为7%.输出光斑具有高斯型强度分布,1W输出时的M2因子约为1.7.
A CW green laser was reported with ceramic Nd：YAG as gain material and KTP crystal as frequency doubler. When the pump power was 21.6 W, the 1064 nm fundamental output was 11.3 W, corresponding to an optical conversion efficiency of 52.3%. When a type-II cut KTP crystal was inserted in the straight cavity as a frequency doubler, the maximum 532 nm green output was 1.86 W, and the optical conversion efficiency was 7%. The one-dimensional intensity distribution of the green facula was of Gaussian type, and the M2 factor was measured to be 1.7 when the output power was 1 W.
