Doppler cooling to the recoil limit by means of sharp atomic transitions with controlled quenching
Doppler cooling to the recoil limit by means of sharp atomic transitions with controlled quenching
In this paper, we develop an analytical approach to Doppler cooling of atoms by one- or two-photon transitions when the natural width of the excited level is so small that the process leads to a Doppler temperature comparable to the recoil temperature. A ``quenching'' of the sharp line is introduced …
