Abstract: We investigate theoretically the laser dynamics of a He–Ne rod laser (λ= 1.15 μm) and the modes of a resonator with simultaneous rotation and harmonic modulation of the resonator anisotropy directions. We find that in both the resonator and the laser natural oscillation modes are possible for which the polarization ellipse rotates at a rate that exceeds the rotation rate of the directions of anisotropy of the modulator. We obtain parameters of the anisotropy and modulation for which this increased frequency of rotation of the polarization ellipse can be observed.
