【Abstract】 Experiments to study the soft X-ray reemission properties from different material heated by the radiation produced by laser plasma are reported. Thermal source is performed with the laser pulse (intensity 1014 W/cm2 ) to act on Au disk target in Xing Guang laser facility, which heated different material. Temporal, spatial and spectral composition measurement is performed with varied soft X-ray diagnostic facilities. Finally, reemission time delay, reemission efficiency, reradiation spectrum construction and delay emission time-space properties of the stagnation plasma are given.更多还原
