Abstract

We study stability and bifurcations of 1D localized structures in a laser with a saturable absorber. Instability leading to oscillating localized structure is described. Our numerical study of light propagation in a dispersive medium with saturable gain and absorption provides evidence for the existence of 3D `laser bullets'.
