摘要：
Dynamics of light bullets in the Raman active and ionized medium was analyzed with the help of moment method. We obtained system of ordinary differential equations for the pulse's parameters such as amplitude, temporal duration, chirp parameter, temporal delay, frequency shift, transverse size and curvature of wave surfaces. Using the Lyapunov method the range of parameters where light bullet is stable was defined.(c) 2022 Elsevier Ltd. All rights reserved.
