Laser-Diode Pumped All-Solid-State Continuous-Wave Ultraviolet Laser at 355 nm
摘要
通过优化设计激光谐振腔,实现了激光二极管(LD)抽运腔内三次谐波转换355 nm紫外激光器的高效率输出。实验中采用复合腔结构,利用BIBOⅠ类临界相位匹配进行腔内和频, 当注入到Nd:YAG和Nd:YVO4晶体的抽运功率分别为20 W和8 W时,获得最大功率为114 mW的TEM00连续波355 nm的紫外激光输出,光-光转换效率为0.4%,4 h功率稳定度优于±3.2%。
Abstract
A laser-diode pumped all-solid-state 355 nm continuous-wave ultraviolet laser with intra-cavity tripling and efficient output was achieved by cavity design optimization. Ultraviolet laser at 355 nm is obtained by using a doubly cavity, and type-Ⅰ critical phase matching BIBO crystal for intra-cavity sum frequency mixing. With incident pump power of 20 W in Nd:YAG and 8 W in Nd:YVO4, TEM00 mode ultraviolet laser at 355 nm of 114 mW is obtained at last, corresponding to an optical-to-optical efficiency of 0.4%, and the power stability in 4 h is better than ±3.2%.
