Gray molasses cooling
http://export.arxiv.org/pdf/1812.09177 Webenhanced gray molasses cooling (GMC). This technique couples traditional polarization gradient cooling with velocity selective coherent population trapping (VSCPT), resulting in large friction forces and low scattering rates in low momentum states. This technique has been experimentally

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 ... Gray molasses is a method of sub-Doppler laser cooling of atoms. It employs principles from Sisyphus cooling in conjunction with a so-called "dark" state whose transition to the excited state is not addressed by the resonant lasers. Ultracold atomic physics experiments on atomic species with poorly … See more Like Sisyphus cooling, the cooling mechanism of gray molasses relies on a two-photon Raman-type transition between two hyperfine-split ground states mediated by an excited state. Orthogonal superpositions of … See more Dressed-State Picture Denote the two ground states and the excited state of the electron $${\displaystyle g_{-1}\rangle , g_{1}\rangle ,}$$ See more • Sisyphus cooling • Raman spectroscopy See more
