Irradiation effects of laser on typical metal targets under tangential airflow

College of Photoelectric Science and Engineering,National University of Defense Technology,Changsha 410073,China

摘要

摘要: 总结了亚音速切向气流在激光辐照典型金属靶过程中所起的作用,提出气流效应主要包括增大靶与外界环境的对流换热强度;移除靶表面的熔化层,加快烧蚀速率;促进靶的氧化反应,有利于靶的烧蚀;空气动力学效应导致靶在熔化之前就可发生破裂等几个方面。对上述气流效应进行了详尽的分析,同时指出应对氧化反应及热力联合效应进行更广泛的实验研究,获得更明确的规律性认识,以便建立统一的物理数学模型,从而为实际的工程应用提供参考。

Abstract: The effects of some metal targets subjected to the laser irradiation and tangential airflow are overviewed. It points out that the airflow usually affects the metal targets in such ways:cooling the targets, removing the melt layer, supporting the combustion reaction and breaking the target prior to melt-through. After analyzing on the airflow effects in details, it suggests that extensive experimental research should be performed for the combustion reaction and thermal-mechanical effect during laser irradiation. By this way the clearer laws can be understood and the unified physical model can be developed for engineering applications.
