Abstract

We have analyzed deep Raman cooling of alkaline-earth atoms with two stable and two excited states in a field of three traveling light waves. It has been shown that the excitation of this system by Raman pulses applied between lowest states of the system can be used to deeply cool its atoms to a temperature that is on the order of or even lower than the temperature determined by the recoil energy.
