摘要
利用热传导理论分析了激光物体相对运动情况下相互作用机理 ,得出了物体在熔化、汽化过程中表面温度与光斑尺寸、焦深及相对运动速度之间的关系 .通过实验 ,设计制作了光学双缝和多缝 ,并用于光学实验 。
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.
