LOW-FREQUENCY DYNAMICS OF LASERS

An approach to nonlinear dynamics of multimode lasers is developed. It is based on the concept of two systems of eigenoscillations: optical modes and relaxation oscillations. The importance of a correct (not ar bitrary) choice of a model is underlined. Characteristic features of t wo different rate equation models are formulated and compared. A metho d of selective perturbation on the system is described which makes it possible to study interrelations between optical modes and relaxation oscillations, and to control dynamical behavior of a laser. The possib ility of using dynamical regularities for solving both applied and bas ic problems is illustrated in several examples. (C) 1996 American Inst itute of Physics.
