Abstract:

The new steady state of the gas - thermo-optical pressure difference is considered. This condition occurs in the gas that is in a closed capillary in the field of resonant laser radiation and a temperature gradient. The pressure difference at the ends of the capillary is determined by the interaction of three fluxes thermal creep, the light-induced drift and Poiseuille flux. Laser radiation and the temperature gradient play the role of thermo-optical piston (TOP) which compresses the gas in different ends of the capillary. The problem is solved based on the linearized Boltzmann kinetic equations that take into account the induced and spontaneous transitions in atoms or molecules. Expressions for the kinetic coefficients defining TOP-effect are obtained in the case of a nearly free-molecular regime. Numerical estimates of the TOP-effect are given for sodium vapor.
