Dynamic modes of generation in He-Ne lasers at nonadiabatic modulation of anisotropy directions

The generation dynamics of a linear He-Ne laser at (lambda) equals 1.15 micrometers with rotation and simultaneous harmonic oscillations of resonator anisotropy directions is investigated theoretically. It has been found that modes with a polarization ellipse rotation with frequency greater than the rotation frequency of modulator anisotropy directions may be possible both in a resonator and in a laser. The two-parameter diagram constructed indicates the regions of `positive' rotation and of torus-attractors with resonant two-period cycles.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
