Abstract:
The processes influencing the formation of the emission polarization of isotropically pumped due lasers are investigated both theoretically and experimentally. In mathematical description of lasing, the system of rate equations for the set of polarization modes is used. The dependences of the gain and lasing intensity on the degree of cavity anisotropy and the pumping power were calculated. Polarization characteristics of the rhodamine 6G laser were studied experimentally as functions of the above parameters. The dependence of the gain factor anisotropy on the degree of cavity anisotropy and the pumping intensity has been revealed. As was established, the dependence of the gain anisotropy on the pumping intensity leads to the dependence of the degree of laser radiation polarization on the pumping power and results in a nonstationary polarization diagram.
