1.3μm全固态激光器在激光雷达、光纤通信、激光医疗等军事和民用领域有着广泛的应用,同时其经过频率变换所获得的红蓝光也是激光彩色显示中的重要光源,因此对1.3μm激光器的研究具有很大的现实意义。但是,相对于1.06μm的情况,激光增益介质在1.3μm的热效应更明显,激光器的效率、输出功率也较低。2003年,A.Minassian等利用掠入射Nd:YVO4板条激光器结构获得了10 W基模 1.3μm all-solid-state lasers are widely used in the fields of military and civil applications such as laser radar, optical fiber communication and laser medical treatment. At the same time, their red-blue light obtained by frequency conversion is also an important light source in laser color display. Therefore, Has great practical significance. However, compared with the case of 1.06μm, the laser gain medium has a more pronounced thermal effect at 1.3μm, and the laser’s efficiency and output power are also lower. In 2003, A.Minassian et al. Obtained a 10 W fundamental mode using a grazing incidence Nd: YVO4 slab laser structure
