Abstract

Abstract We investigate the process of gas trapping by a moving interference lattice formed by laser radiation of nonresonance frequency (the optical gas trapping) with regard for intermolecular collisions. For the transitional regime (when the mean free path of gas molecules λ is less than the lattice period) the energy and momentum transfer from a moving optical lattice to gas is found to realize more intensively than in the case of a free molecular regime. The maximum values of the gas velocity and heating are shown to be determined by the lattice velocity and weakly depend on the laser intensity.
