| 摘 要： | 报道了一种激光二极管(LD)端面泵浦的Nd:YAG声光Q开关高峰值功率266nm紫外激光器。该激光器采用紧凑的平平腔结构,LBO和BBO分别作为其二倍频和四倍频晶体。分别利用高偏振比LD阵列(40∶1)、低偏振比LD阵列(5∶1)及低偏振LD阵列腔内放置布氏片结构进行了实验。当注入功率为25W、调制频率为10kHz时,以上结构分别得到功率0.85,0.61和0.72W的266nm紫外光输出。其中,采用高偏振比LD阵列的输出功率最高,单脉冲能量为85μJ,脉宽为5ns,峰值功率高达17kW,泵浦光到紫外光的光-光转换率达3.4%。

| Abstract: | An efficient laser -diode(LD) pumped Nd:YAG extracavity frequency conversion all -solid -state quasi -continuous -wave(QCW) ultraviolet laser at 266nm was reported. The laser adopted LBO and BBO as the second and fourth harmonic generation crystals, and was pumped by three LD configurations (high polarization LD， low polarization LD and low polarization LD with a Brewster plate) in the experiment. When the pump power was 25 W and the modulation frequency was 10 kHz， 266 nm UV lasers were obtained with the output power of 0.85， 0.61 and 0.72 W, respectively. A high power UV laser was obtained by using high polarization ratio LD with a single pulse energy of 85 μJ， and a pulse width of 5 ns. The corresponding peak power was as high as 17 kW， and the optical -to -optical conversion effi |
