激光驱动铝靶产生冲击波和热波的实验观测和分析

INVESTIGATION ON SHOCK AND HEAT WAVES IN ALUMINUM IRRADIATED BY LASER

在“星光Ⅱ”上 ,使用基频光打靶 ,采用几种厚度的铝介质平面靶 ,进行了冲击波、热波和稀疏波三波相互作用规律的初步研究工作 ,成功地观测到冲击波在前和热波在后的物理图像 ,并发展了相关诊断技术和方法。

Al targets with several th ickness were irradiated using 1.06μm laser on ‘Xingguang Ⅱ’ laser facilit ies.Investigation on the interactions among shock wave,heat wave and sparse wave was primarily done.It was successfully observed that shock wave is in front of heat wave.The related diagnostic methods were developed.
