摘　　要：根据自聚焦透镜折射率的分布特性 ,对其成像原理进行了讨论。将用来耦合泵浦光的自聚焦透镜的一个端面加工成凹面并镀高反介质膜 ,与倍频晶体出射端面构成平 -凹型全固态倍频激光谐振腔。这种激光器谐振腔结构简单、体积小、易于谐振。According to the property of the refracive index distributing in selfoc lens, the imaging principle is analyzed. The surface of a selfoc lens coupling with semiconductor laser is concave and is coated with high reflecting medium membrane. It forms a plane concave cavity in all solid state laser with the plane of a double frequency crystal. This kind of laser cavity has simple structure, small volume, resonance easy and high efficiency as well as stable output.
