报道了用新型络合物非线性光学材料硫氰酸汞镉(CMTC)晶体实现激光二极管室温下直接倍频,产生蓝紫光激光输出。基频光功率为1.98 W,波长为808 nm,用长度为4 mm的CMTC晶体,获得404 nm波长的倍频光功率为11.8 mW,SHG非线性转换效率为0.60%。

A blue-violet laser is described by direct laser diode frequency doubling with a new nonlinear organometallic complex CMTC crystal. At room temperature, a blue-violet light output of 11.8 mW (λ=404 nm) is realized. With a 4 mm-long crystal, a SHG conversion efficiency of 0.60% (λ=808 nm) is obtained.
