Аннотация
The problem of sub-Doppler laser cooling of atoms under "optical molasses" conditions in fields formed by counter-propagating waves with different polarization configurations is considered, with full accounting for quantum recoil effects. It is shown that the distribution of cold atoms is not in equilibrium but can nevertheless be approximated by two Gaussian functions and, accordingly, characterized by temperatures of "cold" and "hot" fractions. A detailed analysis of the atomic fractions and their temperatures depending on the parameters of light fields is carried out. Based on the obtained results, the concept of weighted average temperature can be introduced, which corresponds to the average kinetic energy of atoms.
