| 摘 要： | 在相同的实验条件下,分别采用平平直腔和V型折叠腔对比了Nd:GdYVO4和Nd:YVO4两种晶体的基频和腔内倍频特性.采用平平直腔在抽运功率为10.64 W时分别获得了5.35 W、6.29 W的1.06 μm基频输出,光-光转换效率达50.3%、59.1%,斜效率达58.1%、68.8%;采用V型折叠腔KTP腔内倍频,在抽运功率为6.71 W时分别获得了1.73 W和2.34 W的稳定倍频绿光输出,光-光转换效率达25.8%、34.9%.比较得出,Nd:GdYVO4-KTP绿光激光器的平均输出功率及稳定性均低于Nd:YVO4-KTP绿光激光器.

| Abstract: | Under the same experimental conditions, We used plane-plane cavity and V-shaped folded cavity to compare the fundamental frequency and intra-cavity frequency-doubled characteristics of Nd:GdYVO4 and Nd:YVO4, respectively. With the pump power of 10.64 W, output power(1.06 mm) 5.35 W and 6.29 W were achieved by plane-plane cavity, giving optical conversion efficiency of 50.3％ and 59.1％,slope efficiency of 5.35 W and 6.29 W, respectively. With the pump power of 6.71 W, output power 1.73 W and 2.34 W of stable frequency-doubled green light were achieved by V-shaped folded cavity, giving optical conversion efficiency of 25.8％ and 34.9％, respectively. In summary, the average output power and stability of Nd:YVO4-KTP green light laser are better than Nd:GdYVO4-KTP green light laser. |
