<title>Nonlinear dynamics of lasers considering the vector character of the emitted field</title>

Abstract

A theoretical approach for investigation of amplitude and polarization behavior of a vector class-A laser based on the Jones matrix and vector formalism is considered in details. Exact mathematical expression (under certain conditions) for a new decay rate -decay rate of the electromagnetic field polarization-is derived. It is shown that this constant might be strongly influenced by resonator anisotropy(ies). Amplitude and polarization behavior of the vector laser model taking into consideration the decay rate of the field polarization is investigated for two particular cases of He-Ne slightly a.uisotropic lasers operating at ,\ = 1.15 m (j2 = 1 -ji = 2 transition) and at .A = 1.207 ,am (j2 2 -f 31 2 transition).
