采用磷酸钛氧铷（RTP）电光偏转器作为调Q开关，实现了连续激光二极管（LD）端面抽运Nd:YVO4的激光调Q运转。实验研究了输出耦合镜透射率不同、重复频率不同时激光器调Q的输出特性。当输出耦合镜透射率为60%，在5 kHz重复频率运转时，获得了平均输出功率为1.22 W、脉冲宽度为1.0 ns、峰值功率为244 kW的调Q脉冲输出；当重复频率为20 kHz时，得到的平均输出功率为2.67 W，脉冲宽度为2.2 ns，峰值功率为60.7 kW，对应斜率效率为37%，光束质量因子M2x= 1.226，M2y=1.229。并使用磷酸钛氧钾（KTP）晶体对激光器输出的1064 nm激光进行了腔外倍频，获得了重复频率为20 kHz、平均输出功率为1.33 W的532 nm绿光输出，倍频效率为50%。

Using the rubidium oxygen titanium phosphate (RTP) electro-optic deflector as a Q-switch, we realize a continuous wave LD-pumped Q-switched Nd:YVO4 laser and study the output characteristics in experiments at different output coupling rates and different repetition rates. An output pulse train of 1.22 W average output power with pulse width of 1.0 ns and peak power of 224 kW is obtained at the repetition rate of 5 kHz and an output coupler with transmittance of 60%. Another out pulse of 2.67 W average output power with pulse width of 2.2 ns and peak power of 60.7 kW is obtained when the repetition rate is 20 kHz, the slope efficiency is 37%, and the beam quality factors are M2x=1.226, M2y=1.229. Further, by extra-cavity double-frequency based on a potassium titanium oxide phosphate (KTP) crystal, a green laser at 532 nm with repetition rate of 20 kHz and average output power of 1.33 W is obtained, and the corresponding frequency-doubling efficiency is 50%.
