激光在靶面产生等离子体,对后续入射激光吸收产生屏蔽现象,本文采用探测光路延迟法定量测量了在等离子体演化时间内对入射激光的吸收情况。
The laser produces plasma on the target surface, which can shield the subsequent incident laser absorption. In this paper, the detection laser path delay method is used to quantitatively measure the incident laser’s absorption during the plasma evolution time.
