摘　　要：选择低掺杂浓度的Nd∶YVO_4/YVO_4复合晶体,设计了V字型热不灵敏折叠式谐振腔,利用Ⅰ类非临界相位匹配LBO非线性晶体倍频,当抽运功率为30 W时,获得连续单横模绿光最高输出功率12.9 W,光-光转换效率为43%。当输出功率为11.7 W时,测量其长期功率稳定性优于±0.83%(自由运转3 h),光束质量传输因子M^2小于1.5。A CW laser consisting of a low-doped Nd ： YVO4/YVO4 composite crystal and an Ⅰ-type phase-matching LBO frequency-doubler with a three-mirror Ⅴ-fold thermal unsensibility resonator is designed and constructed. A maximal output power of 12.9 W at 532 nm wavelength is obtained under a pump power of 30 W with an optical- optical conversion efficiency of 43 %. The long term intensity fluctuation over 3 hours free-operation and the beam transfer factor M^2 measured at the output power of 11.7 W were less than ±0.83% and 1.5, respectively.
