We discuss mechanisms of self-organization processes in two-level solid-stateclass-B laser system. The model is considered under assumptions of influence ofnonlinear absorber and external force, separately. It was found thatself-organization occurs through the Hopf bifurcation and results to a stablepulse radiation. Analysis is performed according to the Floquet exponentinvestigation. It was found that influence of the nonlinear absorber extendsthe domain of control parameters that manage a stable periodic radiationprocesses. An external force suppresses self-organization processes. A combinedinfluence of both external force and nonlinear absorber results to morecomplicated picture of self-organization with two reentrant Hopf bifurcations.
