摘　　要：报道了半导体激光二极管(LD)端面泵浦Nd∶GdVO4晶体,KTP晶体腔内倍频实现了531.7 nm连续波绿色激光器.采用简单、紧凑的平凹直腔结构,当注入泵浦的功率为12W时,得到了372 mW的稳定绿光输出,光-光转换效率为3.1%.功率稳定性半小时内优于±1.2%.An LD end-pumped Nd： GdV04, KTP Intra-cavity frequency doubling Green Laser at 531.7 nm is reported. Using simple compact fiat-concave cavity, 531.7 nm continuous green laser is obtained by 1 063.4 nm Intra-cavity frequency doubling with KTP crystal. When the incident pump power is about 12 W, the stable output power of 372 mW was achieved at 531.7 nm. The optical-to-optical conversion efficiency is up to 3. 1% and the power fluctuation is less than ± 1.2% for 0. 5 h.
