Efficient all-optical production of large ${}^6$Li quantum gases using D${}_1$ gray-molasses cooling

A. Burchianti, G. Valtolina, J. A. Seman +5

We use a gray molasses operating on the D${}_1$ atomic transition to produce degenerate quantum gases of ${}^6$Li with a large number of atoms. This sub-Doppler cooling phase allows…
