Abstract
We investigate the process of gas trapping by a moving interference lattice formed by laser radiation of non-resonance frequency (the optical gas trapping) with regard for intermolecular collisions. For the transitional regime (when the mean free path of gas molecules l 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.
