description The particle-in-cell plasma simulation program in two dimensions was developed to display the properties of silver plasma under the effect of Ruby laser 694.3 nm with different intensities; 1012Wcm-2, 1015 Wcm-2, 1018 Wcm-2, and 1020 Wcm-2. The time evolution and the properties of total energy, kinetic energy, and drift energy of the system were examined in the region near the critical density (ne=0.2ncr). The charged particles respond to the laser pulse after a specified period of interaction time in the form of an increase in the energy of the system. This response depends on the intensity of the laser pulse used in this work. A significant increase was observed in plasma energy due to the efficient transfer of laser energy to plasma particles by the Inverse Bremsstrahlung process. The effectiveness of this process is reduced when the laser intensity is increased. This result is shown especially when using 1020 Wcm-2 laser intensity. The results indicated that the plotting of the electron velocity distributions during different time steps of interaction is Maxwellian and it was observed that the curves have a strong energy tail that indicates energy transfers and heating to the plasma.
