Influence of strong laser fields on Coulomb explosions energy losses of correlated-ion clusters in plasmas

摘要

Interactions of correlated-ion clusters with classical plasma targets are studied in the presence of a strong laser field. General expressions of the dynamic interaction potential are derived within the framework of the linearized Vlasov-Poisson theory. Coulomb explosions and the energy losses of the cluster moving in the plasma target are simulated by solving the equations of motion for the constituent ions. Numerical results show that the laser field affects the correlation between the two ions and contributes to decrease of the plasma stopping power, as compared to the laser-free case. In addition, the Coulomb explosions and the energy losses are discussed for a range of laser parameters. (C) 2004 American Institute of Physics.
