| 摘 要： | 提出了有效介电常数模型,利用"流体动力学"模型分析了超短超强激光与团簇相互作用过程中高价电离态离子产生的机制,以及不同波长激光对高价电离态离子产生机制的影响.并在此基础上采用粒子模拟计算了不同电荷态离子的能谱以及总的离子能谱分布.计算结果表明在高电荷态离子的能谱分布上有很长的高能尾部,表明产生了几百keV的高能离子.

| Abstract: | An effective plasma dielectric constant is proposed to modify the resonance absorption based on the hydrodynamic model. Employing this model, the interaction of atomic clusters with high-intensity lasers with different frequency has been studied. Moreover, based on this model, particle simu lation has been employed to simulate the expanding process of Kr clusters in the laser-cluster interaction. The total ion energy spectrum, the energy spectrum of ions with different charge states have been calculated. |
