Paper Abstract

Dynamics of light bullets in the Raman active and ionizing gas was analyzed with the help of moment method. We obtained the system of ordinary differential equations for the pulse’s parameters such as amplitude, temporal duration, chirp parameter, temporal delay, phase, frequency shift, transverse size and curvature. Numerical analysis of this system shows that quasi-stable regime takes place when exist balance between dispersion and nonlinearity, photoionization and stimulated Raman self-scattering with simultaneous suppression of diffraction and ionization divergence by self-focusing.
