本文提出,用外表面镀有高反射率金属膜的椭圆柱玻璃管来代替固体激光器的金属聚光器,在同一台YAG激光器上分别采用两种聚光器对比实验的结果表明,玻璃聚光器的聚光效率与金属聚光器完全相同。
In this paper, we propose to use an elliptic cylindrical glass tube coated with a high reflectivity metal film instead of a metal laser for a solid laser. The results of a comparison of two kinds of condensers on the same YAG laser show that the glass concentrates The condensing efficiency of the instrument is exactly the same as that of the metal condenser.
