| Abstract: | The problem of high-power laser heating up the moving body was studied using the heat conductive theory and the underlying relationship among the surface temperature, the diameter of the light spot, the depth of focus and the moving speed of the body was gained. Through experiment we made two-split and several-split samples for optic interference demonstration and achieving the anticipative effect. |
