| Abstract: | 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. |
