虚共焦腔中存在会聚球面波的实验证明

Experimental demonstration of convergent spherical wave inside virtual confocal cavity

文献［１］认为会聚球面波不满足自再现条件，即腔内不存在稳定的会聚球面波。本文用实验证明了在虚共焦腔中存在会聚球面波，并得到了稳定的会聚球面波输出。

The literature considered covergent spherical wave is not content with self-consistent,the intracavity did not exist stable covergent spherical wave. The artical proves experimental result inside virtual confcal cavity existed covergent spherical wave,and obtained output of stable covergent spherical wave.
