abstract

• We present a lifetime measurement of the level of rubidium. We use a time-correlated single-photon counting technique on two different samples of rubidium atoms, a vapor cell with variable rubidium density, and a sample of atoms confined and cooled in a magneto-optical trap. The 2 level serves as the resonant intermediate step for the two-step excitation to the level. We detect the decay of the level through the cascade fluorescence of the 2 level at 780 nm. The two samples have different systematic effects, but we obtain consistent results that averaged give a lifetime of 45.57. © 2005 The American Physical Society.
