目前，增益介质中有害的热效应限制了工作在4F_（3/2）→ 4 I_（9/2）三能级跃迁的Nd：YAG激光器输出功率的提高。使用双包层平面波导，一个高效的946 nm激光器已被证明产生35 W的输出功率与相应的斜率和光-光转换效率分别为56%和50%，分别。性能和进一步的功率缩放的可能性进行了讨论。
To date increasing the output power of Nd:YAG lasers operating on the three-level4F3/2→4I9/2transition has been restricted by detrimental thermal effects in the gain medium. Using a double-clad planar waveguide, an efficient 946 nm laser has been demonstrated that produced 35 W of output power with corresponding slope and optical-to-optical conversion efficiencies of 56% and 50%, respectively. Performance and further power-scaling possibilities are discussed.
