Chaotic lasing regimes in the unstable cavity of an inhomogeneously pumpedfast-flow laser

The scenario for the development of the characteristics of chaotic emission by a fast-flow laser with an unstable cavity and spatially inhomogeneous p umping was investigated numerically. The complex evolution of the dynamic r egimes, accompanied by a number of bifurcations, was investigated by varyin g the controlling parameter within the limits of the region of existence of chaotic lasing. It was found that, under certain conditions, the chaotic d ynamics undergoes a transition to regular dynamics. The Fourier emission sp ectra were calculated, the dimensions of the chaotic attractors were determ ined, and Poincare maps were constructed.
