They share many common characteristics with other multi-dimensional phenomena and their study remain an open challenge. Here, we report semi-rotating and rotating light bullets from pulsating dynamic when a suitable ansatz function is chosen. Using the complex cubic-quintic Ginzburg-Landau equation model and thanks to a variational method known as the collective variable approach, we can observe stable pulsating light bullet. The influence of the initial conditions leading to an asymmetric rotating light bullet in the transverse plane, are investigated. http://pubs.sciepub.com/ijp/11/1/3/ijp-11-1-3.pdf pulsating light bullet rotating light bullet complex Cubic-Quintic Ginzburg-Landau Equation dissipative soliton collective variable approach spatial-Temporal Pulse semi-rotating light bullet
