$\Lambda$-Enhanced Gray Molasses Cooling of ${}^{85}$Rb Atoms in Tweezers Using the D${}_2$ Line

Deon Janse van Rensburg, Rogier Venderbosch, Yuri van der Werf +5

We demonstrate the implementation of $\Lambda$-enhanced gray molasses cooling on the D${}_2$ line of ${}^{85}$Rb atoms in an optical tweezer array. This technique yields lower atomic tempera…
