The model is considered under assumptions of influence of nonlinear absorber and external force, separately. It was found that self-organization occurs through the Hopf bifurcation and results to a stable pulse radiation. Analysis is performed according to the Floquet exponent investigation. It was found that influence of the nonlinear absorber extends the domain of control parameters that manage a stable periodic radiation processes. An external force suppresses self-organization processes. A combined influence of both external force and nonlinear absorber results to more complicated picture of self-organization with two reentrant Hopf bifurcations.9 pages, 13 figuresAdaptation and Self-Organizing Systemstext
