In this paper, one-dimensional kinetics simulation was studied on e-beam pumped KrF laser in Ar/Kr/F2 mixtures, taking account of 24 species particles and 119 reaction channels. Its physical mechanism and mathmatical handling method were studied in detail. Using this model, simulations were performed and compared with the experimental results abroad and were in good agreement with them. Also simulations were performed and compared with the hundred-joule excimer laser, some laser parameters varying on time and longitudinal position were obtained and analysed.The theoretical results of one-dimensional model were compared with that of zero -dimensional model finally.
