Ground-State Cooling of a Single Atom in a High-Bandwidth Cavity

WebAnd in order to cool down 39K atoms beyond the Doppler cooling limit, one can use degenerate Raman sideband cooling via the 4S1/2 to 5P1/2 transition. Finally, in the … WebDec 28, 1998 · With degenerate Raman sideband cooling we achieve a vibrational ground state population of 80% for the steep trapping direction. Collisional coupling enables us to cool the spin-polarized gas in 3D without loss of atoms to a peak phase space density of 1/180 at a mean temperature of 2.8μK and a density of 1.4×1013cm−3.

Raman Cooling to High Phase Space Density - Massachusetts …

WebRaman sideband cooling is a method to prepare atoms in the vibrational ground state of a periodic potential and cool them below recoil limit. It can be implemented inside an … WebMay 1, 2003 · Abstract We propose a cavity-based laser-cooling and trapping scheme, providing tight confinement and cooling to very low temperatures, without degradation at high particle densities. A bidirectionally pumped ring cavity builds up a resonantly enhanced optical standing wave that acts to confine polarizable particles in deep potential wells. Web(a) Geometry of the experimental setup with 795nm ray of small, nearly one-dimensional condensates has optical pumping and Raman coupling beams, and 1064nm been prepared using degenerate Raman sideband cool- trapping beams.
