Abstract
Using the linearized hydrodynamic-Poisson equations, we describe electronic excitations of electron gas in solids, and derive general expressions for the induced potential in the target, and the interaction force among the ions within a molecule, in the pre-sence of a laser field. Based on the numerical solution of equations of motion for the constituent ions, the Coulomb explosion patterns and the molecular energy losses are studied for a range of laser parameters. It has been found that by increasing the laser intensity, the wake effects in the interaction potential become weaken. This weans that the deflection of the molecular axis to the direction of the projectile velocity is not significant, and the energy loss of the molecular ions is also reduced.
