|Title:||Two-photon Doppler cooling of alkaline-earth-metal and ytterbium atoms|
|Abstract:||The possibility of laser cooling of alkaline-earth-metal atoms and ytterbium atoms using a two-photon transition is analyzed. We consider a S-1(0)-S-1(0) transition with excitation in near resonance with the P-1(1) level. This greatly increases the two-photon transition rate, allowing an effective transfer of momentum. The experimental implementation of this technique is discussed and we show that for calcium, for example, two-photon cooling can be used to achieve a Doppler limit of 123 muK. The efficiency of this cooling scheme and the main loss mechanisms are analyzed.|
