LD End-pumped Nd:YAG/BIBO TEM_(00) Mode Blue Laser

从理论上分析了准三能级系统946 nmNd:YAG全固态激光器运转的条件,并比较了几种不同的倍频晶体的特性,给出内腔倍频获得473 nm蓝光发射的方案。用波长808 nm、输出功率为2.2 W的半导体激光器泵浦Nd:YAG,采用内腔倍频的方法,在一定的温度下,用Ⅰ类临界相位匹配B IBO晶体倍频获得了473 nm 26.5 mW的单模连续蓝色激光输出,功率波动小于±5%。

In this paper, the authors design and build a LD end-pumped Nd：YAG/BIBO TEM00 mode blue laser. Considering the theory of Nd：YAG 946 nm quasi-three-level laser system and Comparing the properties of BBO, LBO and BIBO for frequency doubling at 946 rim, the authors present the way to realize the operation of 473 nm all-solid-state blue laser. With incident pump power of 2.2 W, output power of 26.5 mW at 473 nm can be obtained using an intra-cavity doubling crystal of BIBO. The longtime stability of the output is ±5%.
