| 摘 要： | 本文应用一维双温激光靶相互作用简化物理模型对脉宽为10ns级系列脉冲激光照射真空中铝靶产生的LSD波进行了数值研究。对于单个脉冲宽度τ_p=10ns,脉冲间距τ_p=50ns的系列脉冲情况,得到了LSD波点火的脉冲个数N_(LSD)与单脉冲归一化强度(I_s/I_(LSD))的关系。分析了系列脉冲激光LSD波点火的积累效应以及LSD波的屏蔽效应。

| Abstract: | The LSD waves produced by irradiating aluminum targets in vacuum with a series of laser pulses have been studied numerically using the physical model of 1 -D and two -temperatures for laser -target interactions. The relation between the pulse number NLSD of LSDWs ignition and the normalized intensity (I0/ILSD) has been obtained for pulse duration tp=10ns, and time gap between pulses tr = 50ns. The accumulation effects of LSDWs ignition and shielding effects of LSD Ws have been analysed. |
