We discuss the problem of excess noise in lasers of different dynamical classes, as well as adequate models for the description of such noise. It is shown that the excess noise in lasers is caused by mode-mode coupling. The linear coupling leads to t

The dynamics of a two-mode laser is studied in the presence of a selective saturable absorber interacting only with one of the modes. The specific nature of the system is determined by the presence of the out-of-phase relaxation oscillation, which be

Experimental results on the low-frequency polarization dynamics of a free-running Nd-doped optical fibre laser and a fibre laser with derivative feedback are presented. It is found that the power spectrum of each polarization mode reveals three relax

We study analytically the Tang, Statz and deMars rate equations describing a solid-state Fabry-Perot laser. When the modes have equal gains, there is a critical number of lasing modes, above which the low-frequency relaxation oscillations responsible

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 arbitrary) choice of a model is underlined

The intensity fluctuations in multimode lasers with slow relaxing laser media are theoretically investigated. The power spectra corresponding to different correlation conditions between the noise sources inserted into individual modes are calculated

The results are given of an analysis of the stability of the travelling-wave regime in a ring laser model that takes account of the real structure of the gain profile of neodymium-doped yttrium aluminate garnet. A travelling-wave steady state of the

Relaxation oscillations have been studied both theoretically and experimentally in a multimode YAG laser in the presence of a derivative feedback. In addition to the standard relaxation oscillations, discrete low frequency components are present in t

A dynamic theory of a bidirectional ring laser with a slow-response active medium is developed. This theory takes account of certain specific factors applicable to semiconductor and some solid-state active media, such as the diffusion of the light-em

The two-mode semiconductor laser rate equations are generalized to account for the diffusion of free carriers. Using the diffusion coefficient as a control parameter we analyze the competition between small-scale and large-scale gratings in the laser
