摘　　要：研究了飞秒强激光与Ar原子团簇相互作用时的电离机制及库仑爆炸过程 ,建立了一个简化的模型计算相互作用产生的离子能谱。计算结果与实验结果较为吻合 。The interaction between a femtosecond laser pulse and Ar atomic clusters was studied, and a simple model was established to calculate the energy spectrum of ions emitted from the exploded clusters. The calculating results are in agreement with the experimental data, and it can explain the main characters of energy peaks in energy spectrum.
