Title: | Two-photon doppler cooling of alkaline-earth-metal and ytterbium atoms |
Author: | Magno, Wictor C. Cavasso Filho, Reinaldo L. Cruz, Flavio C. |
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. |
