摘要
在“星光Ⅱ”上 ,使用三倍频激光打三种厚度 (6 ,10和 2 0 μm)的铝介质平面靶 ,采用光学条纹相机记录冲击波图像 ,对热波和稀疏波进行测量 ,同时开展冲击波、热波和稀疏波三波相互作用规律的初步研究 ,采取多种措施成功地观测到冲击波在前、辐射热波在后。
Aluminum targets with three kinds of thickness (6,10 and 20 μm) were driven by laser at 0 35 μm wavelength on 'Xingguang Ⅱ' facilities. Shock wave images were recorded by optical streak camera, heat wave and rarefaction wave images were measured using X ray streak camera. The experimental investigation on the interactions among shock wave, heat wave and rarefaction wave was made. Through several measure technique, the three wave interaction physical images were obtained in which shock wave early heat wave was late and rarefaction wave was last.
