Paper Abstract

The surface micro-deformations of a cavity copper mirror, an annular channel copper mirror, a multi-layer copper mirror and a sandwich copper mirror are tested when the mirrors are irradiated by high power laser and cooled by water. The test result shows that the surface deformation values of the multi-layer copper mirror and the sandwich copper mirror are much smaller than the cavity copper mirror and the annular channel copper mirror, and the multi-layer and the sandwich copper mirror can meet the requirement of a high power laser system on very small mirror surface deformation.
