Polarization instability in a two-frequency gas laser with a weakly anisotropic cavity
- Stepanov Institute of Physics, Minsk (Belarus)
On the basis of the formalism of Jones vectors and matrices, lasing equations are derived for a two-frequency gas laser with arbitrary magnitude and type of cavity anisotropy with longitudinal magnetic field applied to the active medium. The case of linear phase anisotropy is examined in detail. In lasers working on J{implies}j + 1 transitions, the feasibility of polarization instability is shown in the absence of any external action. Polarization multistability is revealed. Polarization dynamics of a laser with an active medium placed in an axial magnetic field is studied. Single-wave and two-wave self-oscillation regimes of lasing are revealed. The theoretical results obtained in this work agree with familiar experimental data. 28 refs., 6 figs.
