Abstract

We investigate the region of validity of the semiclassical approach to simulating laser cooling. We conclude that for the commonly used πxπy polarization-gradient configuration, the semiclassical approach is valid only for transitions with recoil parameters εr on the order of 10−4 or less. For the standard laser-cooling transitions only the transitions in Rb and Cs satisfy this condition. For the Doppler and σ+σ polarization-gradient configuration the semiclassical approach is valid for most of the commonly used transitions; however, the expected gain in execution speed compared with quantum Monte Carlo calculations has been realized only in part. A drastic reduction in calculation time is to be expected by implementing an analytical approach to the long-term contribution of the diffusion coefficient.
