Two-Photon Doppler cooling of alkaline-earth-metal and ytterbium atoms

Wictor C. Magno, Reinaldo L. Cavasso Filho, Flavio C. Cruz

A new possibility of laser cooling of alkaline-earth-metal and Ytterbium atoms using a two-photon transition is analyzed. We consider a ${}^1{S}_0$ - ${}^1{S}_0$ transition, with e…
