Abstract
Using a weakly nonlinear analysis, we study the behavior of a homogeneously broadened laser in the vicinity of the second threshold. We show that the dynamics is described by a complex Ginzburg-Landau equation coupled to a Fokker-Plank equation. Although the cubic term of the Ginzburg-Landau equation is destabilizing for all parameter values, bounded solutions exist because of the strong nonlinear dispersion (''dispersive chaos''). A careful numerical study of the original Maxwell-Bloch equations is also carried out to investigate the role played by off-resonant solutions.
