【 摘 要 】

An approach of the empirical modes with a variable spatial-temporal structure is proposed and developed for the analysis of non-stationary nonlinear dynamics of the multimode superradiant lasers with a low-Q cavity and a strong inhomogeneous broadening of lasing transition in an active medium. It is shown that the approach makes it possible to analyze a number of complicated dynamical phenomena in an ensemble of the strongly interacting centers which constitute the active medium and are exposed to CW pumping.
