We employ semiclassical theoretical analysis to study laser cooling of free atoms using three-level cascade transitions, where the upper transition is much weaker than the lower one. This represents an alternate cooling scheme, particularly useful for group II atoms. We find that temperatures below the Doppler limits associated with each of these transitions are expected. The lowest temperatures arise from a remarkable increase in damping and reduced diffusion compared to two-level cooling… Expand

We analyze laser cooling of two-electron atoms with three-level cascade transitions, involving the usual 1S0–1P1 cooling transition coupled to either 1S0 or 1D2 states. We numerically calculate… Expand
