Continuous cooling below the Doppler Temperature of Sr in a Two-Color Magneto-Optical Trap — •Shubha Deutschle, Milán Negyedi, Andreas Günther, Lörinc Sárkány, and József Fortágh — Physikalisches Institut, Universität Tübingen
We use the 5s2 1S0 ground state and the 5s5p 3P2 metastable state of Sr for two-stage laser cooling in a two-color magneto-optical trap. 88Sr atoms are precooled operating on the 5s2 1S0 - 5s5p 1P1 transition. Cooling below the Doppler limit is achieved using the 5s5p 3P2 - 5s5d 3D3 transition.
