Influence of a finite polarization relaxation time on the transverse structure of the optical field of a wide-aperture laser

It is investigated the effect of a finite cross-relaxation rate on the transverse radiation dynamics of a wide-aperture laser. The spatiotemporal structure of the optical field in wide-aperture laser with different cavity geometry and the finite mirrors is obtained. The conditions are found for the emergence of periodic autowaves for positive and negative frequency detuning. These conditions are shown to depend strongly on the cross-relaxation rate.
