【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1．06μm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。更多还原

【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(1.06μm) 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.更多还原
