采用准相位匹配的KTP晶体对全固化Nd∶YVO4连续输出的 10 6 4nm单频激光进行外腔谐振倍频 ,当倍频腔的红外输入功率为 15 0mW时 ,获得 76mW的单频绿光输出 ,最大倍频转换效率为 5 0 6 %。
A KTP crystal with quasi-phase matching is used to perform the external cavity harmonic multiplication on a 1064nm single-frequency laser with an all-solidified Nd: YVO4 continuous output. When the frequency doubling cavity has an infrared input power of 150mW, a single-frequency green light output of 76mW , The maximum frequency conversion efficiency of 506%.
