The invention discloses a laser resonant cavity with a corner reflector, including full-reflector, plane output mirror and laser working medium, where the full-reflector is a corner reflector and felted of three plane reflectors, where they are placed across and perpendicular to one another and their reflecting surfaces are all plated with high reflection film. It outputs a solid parallel light beam, where near-field facula strength is uniformly distributed and far-field light energy is centralized, the emitting angle is extremely small, the mode bulk is large, it is convenient to adjust and works extremely stably. It can be used in a gas or solid laser, or a high-power or medium- and small- power laser. 本发明公开了一种带角隅反射镜的激光谐振腔。包括全反射镜、平面输出镜及激光工作介质，全反射镜为角隅反射镜，由三个平面反射镜粘接而成，它们交叉放置且相互垂直，其反射面均镀高反膜。该谐振腔输出实心平行光束，近场光斑光强分布均匀，远场光能集中，发散角极小，模体积大，调整极其方便，工作极其稳定。可以用于气体或固体激光器，高功率或中小功率激光器。
