Abstract: In this paper we used one-dimentional non-LTE laser irradiated code to simulate the laser-produced plasmas conditions of thin middle Z targets with high intensities (about 10¹³W/cm²)irradiation.Following physical processes are considered; bremsstrahlung,radiative ionization,collisional ionization by electrons and their inverse processes, Compton scatterion. Fokker-Planck approximtaion is used in Compton scattering; The thermal flux limits are taken for electrons and ions in the calculating and the multigroup flux-limited diffusion approximation is taken for the radiative transport equations.Using average-atom model to calculate the population probabilities of atoms. Laser absorption via inverse bresstr-ahlung is considered to be the most important in our simulation.Using, laser beams with intensities 5×10¹³W/cm² and 1×10¹⁴ W/cm², λ_L=0.53μm, τ=450ps to irradiate thin Se target from single-side and double-sides separately, the computational results for laser-produced plasmas conditions are good agree with experimental results.
