The purpose of this research is to study the interaction of femtosecond laser pulses with atomic clusters of Ar. Hot and high-energy electrons, high charge state of ions and X-ray photons are the production of the interaction. These products are the result of ionization, heating and expansion of the cluster that is described with nano-plasma model. Numerical simulation of this work is done by particle in cell (pic) method. To investigate the influence of the shape of the laser pulse, the laser pulse is used as a secant hyperbolic. The evolution of the field inside the cluster, electron energy, ion charge state, ion and electron density of the cluster for the various intensity are calculated. The results agree well with the experimental findings.
