Abstract

Abstract An analytical estimation of the parameters of light bullets formed in the region of anomalous group dispersion in dielectrics under conditions of tunneling photoionization has been carried out. A system of ordinary differential equations for the parameters of a laser pulse is obtained by the method of moments. A new analytical approximation is proposed for calculating the contribution of tunneling ionization. With the help of Lyapunov’s stability theory, a quasi-stationary solution of this system and conditions for a quasi-stable propagation regime are found.
