| 摘 要： | 利用泰曼干涉仪及图像处理系统对强激光作用下不同冷却结构镜片包括空腔、环形通道几何结构铜镜的变形进行了实验研究，对其变形规律、变形机理作了探讨和分析。设计了一种新型多层冷却结构铜镜。将这几种铜镜的变形作比较．结果表明新结构铜镜不仅热变形小．而且由冷却流体压力引起的附加变形也很小．为有效控制强激光系统中镜片表面变形提供了有效途径。

| Abstract: | The distortion mechanism of high power laser mirrors is discussed. The de formation of water-cooled cavity copper mirror and annular channel copper mirror is tested by a Twyman-Green interferometer and image processing system. And a new kind of copper mirror is proposed. Compared with the other mirrors,the new mirror has not only a small thermal deformation caused by incident laser but also a very small pressure de formation yielded by the cooling fluid. |
