本文报道了在双模He-Ne激光器中,引入偏振各向异性而使激光偏振输出表现为多稳行为,并对这种现象给予了定性解释。

It is reported that the multistability behavior can be observed in a He-Ne laser, into which a anisotropic polarized loss is introduced. This phenomenon is explaned as a competition between the saturation-induced polarization perference and the anisotropism of the laser, as well as the effect of fluctuation on the modes with equal resonance frequency and different polarization directions.
