摘　　要：通过在不同的环境气压下拍摄Nd：YAG脉冲激光烧蚀金属Cu诱导发光的发光羽，提出了发光羽的分区模型．并用之定性地解释了所观察的现象，认为不同烧蚀区域的发光机理不同。The photographs of optical plume from laser ablation of metal Cu are maken. Theeffects of pressure over the range of 1. 33kPa to 101. 3kPa on plume is studied, The results are qualitatively explained using a simple model based on plume is made of three different ranges. In these ranges,the mechanism of ablation is different from one another.
