| 摘 要： | 为了得到高效的腔外频率变换355 nm紫外激光输出，提出了一种利用３块LBO作为非线性频率变换晶体的新方案。采用LD端面泵浦Nd：YAG声光Q开关激光器作为基波源，当入射泵浦功率为25 W、调制频率12 kHz时，获得了6.2 W的1 064 nm激光输出，经过非线性频率变换后，获得了2.7 W的紫外355 nm激光输出，光-光转换率43.4%。

| Abstract: | High efficiency extra-cavity third harmonic generation(THG) of 355 nm beam has been developed.A laser diode(LD) end-pumped,acoustic-optical Q-switched Nd:YAG laser was used as the fundamental wave source.With an input pump power of 25 W,the average power of 6.2 W at 1 064 nm was generated with the repetition rate of 12 kHz.Using the extra-cavity frequency conversion of three critical phase match LiO3O5(LBO) crystals,2.7 W third harmonic radiation at 355 nm was obtained.The optical-to-optical(1 064 nm to 355... |
