摘　　要：阐述了“猫眼效应”的基本原理,分析了将“猫眼”目标作为激光谐振腔腔镜,取代普通激光器球面腔镜,获得激光振荡的可能性;计算了“猫眼”目标作为激光腔镜时的等效反射率,指出利用激光在其焦平面的聚焦特性实现激光干扰的新方法。并在实验中得到证实。In an optical system,“cat eye effect” can be mode le d as a focal lens system.Based on the model,with the property that it can refle ct the input laser exactly back along the direction the laser incides,a “cat e ye” system can be applied as an equivalent laser resonant mirror to achieve the laser resonance.At the same time,the equivalent reflectivity of the “cat eye ” system has been calculated.The experimental results have also proved this poi nt of view.The laser resonance has been obtained with deferent mediums at the fo cal plane of our simulated “cat eye” system and all these mediums have been de stroyed by the focal laser spots.
