Webcooling stage. This report is organised as follows: in Sec. 2 our experimental setup is presented and we give an explanation of the cooling steps that will be implemented. In Sec. 3 the cooling process involved in gray molasses is presented. Finally, in Sec. 4 the laser system used for gray molasses cooling is explained in detail. 2 ...
(PDF) Laser cooling of cesium atoms in gray optical molasses …
WebWe find that our gray molasses cooling scheme brings all atoms from a pre-cooled temperature of 60 µK to 8 µK in 3.5 ms, thus insuring that light-assisted losses are … WebOct 1, 2024 · For the demonstration of our stray field compensation method, we use D1-line gray molasses cooling of K, but the technique can be applied to any species where cooling relies on coherences between hyperfine levels of the ground state. The key advantage of our approach is its speed. creed coach
Optimization of gray-molasses cooling. (a) Temperature T (blue …
WebThe requisite cooling can alternatively be provided by -enhanced gray molasses (GM) on the D 1 transition [15], which has limiting temperatures far below those of the 39 K D 2 bright molasses. The ... WebJun 18, 2014 · 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 us to lower the initial temperature of 10$^9$ atoms from 500 to 40 $\mu$K in 2 ms. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. creed coffee table
