Abstract : A previously developed electron cascade model is modified and applied to investigate the breakdown and plasma formation and its propagation in the focal volume . The study is devoted to investigate the breakdown of Argon over a pressure range 0.013-100 atm induced by 532 nm of Nd:YAG laser with pulse length 8 ns and maximum in energy 500 mJ. The model solves the time dependent Boltzmann equation and set of rate equations that describe the change of the excited states population .The result of computations revealed the validity of the model . More over the calculation of the EEDF and its parameters showed the correlation between gas pressure and physical processes responsible for the gas breakdown . The study of plasma propagation in the focal volume in also presented in this work
