New Journal of Physics 13(2): 023012.1367-2630http://nrs.harvard.edu/urn-3:HUL.InstRepos:8886699Cold and optically dense gases of atomic rubidium are produced using buffer gas cooling in combination with rapid, high-flow vapor injection. The observed rubidium density is 3 × 10\(^{12}\)cm\(^{−3}\) at a gas temperature of ∼20 K, leading to an optical density of the order of 200.en-USatomic and molecular physicsatom cooling methodsJournal Article2012-06-1510.1088/1367-2630/13/2/023012
