【摘要】 研究了Ar原子团簇在飞秒强激光作用下的电离机制,考虑了团簇经过库仑爆炸过程和流体力学膨胀过程两种膨胀机制情况下,对离子能谱进行了计算.计算结果与实验结果基本符合,能够很好地解释离子高能端特征,对低能端的能谱也进行了分析.更多还原

【Abstract】 The ionization mechanism of the Ar atomic-clusters irradiated by a femtosecond laser pulse is studied. Ionic energy spectrum is calculated by taking into account the atomic-cluster Coulomb explosion and hydrodynamic expansion. The calculation results agree with experimental data, and can (explain) ionic characteristics in the high-energy region. Energy spectrum in the low-energy region is also analyzed.更多还原
