Paper Abstract

The results of computer modelling of the transverse field pattern dynamics in a unidirectional ring laser with the fast relaxed active medium of arbitrary optical thickness are presented. In the theoretical model the configuration of the cavity having the spherical mirrors and apertures is considered. Numerical results are obtained for the symmetrical cavity. The modes with radial and azimuthal indices of up to 10 and 9, respectively, were taken into consideration. The regimes obtained include the steady-state regimes with distorted modes, quasi-periodic oscillations regimes, lock-in regimes when variations of the laser gain and optical power of the mirrors do not lead to variations of the transverse mode beat frequency. The optical vortices (defects) and their dynamics were demonstrated.
