摘　　要：激光二极管抽运的单块非平面环形腔固体激光器具有结构稳固、效率高等优点 ,在一定的纵向磁场作用下 ,可形成单向行波振荡 ,纵向抽运时就可得到较高功率的单频输出 ,有广泛的应用前景。文中在详细讨论了非平面单向行波环形腔形成单频的原理基础上 ,研究了国际上流行的“三角形”单块非平面环形腔 ,并用此种腔型得到 2 70 m W的基横模单纵模 1.0 6μm激光 ;同时提出了所设计的非平面环形腔“梯形环形腔”和“角锥棱镜式环形腔”。由于它们工作原理相近 ,统称它们为“泛三角形非平面单向行波环形腔”。Diode pumped monolithic nonplanar ring laser has the advantages of compactness, reliability and high efficiency. When it was placed in a magnetic field, a unidirectional travelling wave can be obtained with a high power single frequency output. 270 mW single frequency, TEM 00 output has be obtained from a Nd∶YAG monolithic nonplanar ring laser. The working principles of this kind of laser is discussed in detail, and two kinds of new nonplanar cavities are proposed. Because of the similarity of the working principles, these kinds of nonplanar ring cavities are called the pan triangle nonplanar unidirectional ring cavity.
