The laser cascade ionization is a long distance,non-lethal,electrical conduction weapon,and air ionization and breakdown is the key of the laser cascade ionization.The mathematical model was established according to the theory of laser air ionization.The breakdown process was simulated by using MATLAB software.The different actions between the laser and the air were obtained,and the influences of different conditions on the breakdown process were analyzed.Finally the minimum initial power density of the air breakdown was achieved.
