| Abstract: | Using the perturbed theory, the plasma channel produced by ultra-short ultra-high power laser pulses is considered. Under the actions of recombination, attachment and detachment, the perturbed asymptotic expressions of the density of each kind of charged particles in the course of evolution of the plasma channel are obtained. The influence of each action on the evolution and life_time of the channel is discussed. |

| Keywords: | density laser pulse plasma channel perturbation |
