【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 1×10 14 W/cm 2) to act on Au disk target at the Xin Guang laser facility, which heat different material. Temporal, spatial and spectral composition measurement is performed with verious soft X-ray diagnostic facilities. Finally, reemission time delay, reemission efficiency, reradition spectrum construction and delay emission time-space properties of the stagnation plasma of different material heated by the radiation were given.更多还原
