| 摘 要： | 本文分析了自加热式铜蒸气激光器放电管内的热气体透镜效应,并指出不同的铜蒸气激光器在稳定工作时可能等效为正透镜,也可能等效为负透镜。在实验部分,本文给出了热气体透镜焦距与输入功率、缓冲气体压强的关系,描绘了热气体透镜从负透镜变化到正透镜的动态过程。

| Abstract: | Analysis of the thermal gas lens in the discharge tube of a self-heated copper vapor lasers (OVL) is given. For the different schemes of copper vapor laser, it has been found that the steady-state OVL can be equivalent to a convex lens or a concave lens. As results of the experiment, the relations between the focal length of the thermal gas lens and the input power and buffer gas pressure are presented. The evolution process of the thermal gas lens from concave to convex lens is described. |
