Polarization Switching with Sodium Vapor in a Fabry Perot
It was first predicted by Kitano et al.  that an optical cavity which contained three-state atoms (in the so-called lambda configuration) would show switching and hysteresis in the polarization state of the output as one varied the input power. Their model was subsequently generalized to include saturation effects  and a model was developed using a more realistic atomic model, the J = 1/2 to J = 1/2 transition . Furthermore, it has been predicted that when the atomic susceptibility is primarily dispersive a self-pulsing of the polarization state, with period doubling bifurcations leading to chaotic behavior, can occur [2,3b]. A different type of self-pulsing has been predicted in the case of an applied magnetic field with a direction perpendicular to that of the radiation field wave vector .
