摘　　要：The propagation of ultra-short light pulses with nonlinear chirp and arbitrary amplitude profile is treated by using first-order and second-order intensity moments in temporal domain.A generalized pulse complex pareinieter P^(-1) is introduced and its propagation law through dispersive systems is derived.The pulse quality factor M:is introduced.As an example,the propagation of pulses with sech-type amplitude proHle through dispersive media is included.This method is proved to be a simple way to treat the propagation of non-Gaussian pulses through dispersive system compared with the temporal integral.
