摘　　要：Diode pumped monolithic nonplanar ring laser has been developed, yielding single frequency laser and has the advantages of compactness, reliability and high efficiency. Its principles are given in detail and a monolithic nonplanar ring laser is designed. As a result, a laser of hundreds milliwatts cw single frequency output was built up, placed in a magnetic field and pumped by LD. The optical conversion efficiency was more than 15% and the slope efficiency more than 30%. The laser beam had a good quality, with M 2 about 1 2.研制了具有结构紧凑、稳固、单频输出效率高等优点的半导体激光器 (LD)泵浦的单块非平面环形腔单频固体激光器 .在详细论述单块非平面环形腔固体激光器形成单频的原理基础上自行设计了单块非平面环型腔单频激光器系统 .近期的实验结果为 :获得单频激光输出功率2 70mW ,光光转换效率在 15%以上 ,斜效率可高于 30 % ,输出激光光束质量接近衍射极限 ,测量得到光束传输因子M2 约为 1 2 .
