Multistability of States of a Molecular Gas with the V--T Relaxation Time Dependent on the Vibrational Energy

摘要

The possibility of realizing multistability of states under the action of IR radiation on a molecule under conditions of nonlinear absorption of light energy and dependence of the V--T relaxation time on its vibrational energy is shown.A two-wave optically bistable arrangement potentially having a highly contrasting range of states is proposed.The nonlinear dependence of the V--T relaxation time on the vibrational energy is shown to allow the realization of optical bistability based on the absorption of light energy at the frequency the fundamental vibrational transition.
