以６７９ｎｍ的激光二极管泵浦１ｍｍ厚掺杂摩尔分数为０．０２２ＣｒＬｉＳＡＦ，用ａ－切割的类非临界位相匹配的ＫＮ晶体进行内腔倍频。在吸收功率为２５６ｍＷ时，得到了峰值３．１５ｍＷ、波长为４３１．７ｎｍ的ＴＥＭ００模蓝色激光输出，激光阈值为９６ｍＷ，斜效率为１．９７％。通过改变ＫＮ晶体的温度，实现了波长范围在４２３．４～４４５．５ｎｍ之间的连续可调谐蓝色激光输出。
The 679nm laser diode pumped 1mm thick doped with a molar fraction of 0.022CrLiSAF, with a-cut like non-critical matching phase KN crystal for intraluminal frequency doubling. At an absorbed power of 256 mW, a TEM3 mode blue laser with a peak of 3.15 mW and a wavelength of 431.7 nm was obtained with a laser threshold of 96 mW and a ramp efficiency of 1.97%. By changing the temperature of the KN crystal, a continuous and tunable blue laser output with a wavelength range of 423.4 ~ 445.5nm is achieved.
