摘　　要：报道了一种采用光纤耦合激光二极管阵列(LDA)端面泵浦Nd∶YVO4激光晶体、Ⅰ类临界位相匹配BiB3O6(BiBO)腔内和频实现全固态连续橙黄色激光输出的实验结果。波长为593.5 nm的橙黄色激光是由Nd∶YVO4晶体1064 nm和1342 nm双波长非线性和频产生的。当泵浦功率为27.5 W时,得到橙黄色激光最大输出功率3.6 W,光-光转换效率高达13.2%,据我们所知,这是目前利用腔内和频Nd∶YVO4激光器获得593.5 nm橙黄色激光输出的最高效率。A design of laser-diode array （LDA） end-pumped Nd：YVO4 laser that generates simultaneous laser action at wavelengths 1064 nm and 1342 nm is presented. Using type-I critical phase matching （CPM） BiB306 ,593.5 nm continuous-wave （cw） yellow laser was obtained by 1064 nm and 1342 nm intracavity sum-frequency mixing. The maximum laser output power of 3.6 W is obtained when an incident pump laser of 27.5 W is used. The optical-to-optical conversion is up to 13.2%. To the best of our knowledge,this is the highest conversion efficiency at 593.5 nm by an intracavity sum-frequency Nd：YVO4 laser.
