Measurement of excited-state lifetime using two-pulse photon echoes in rubidium vapor

Eric Rotberg, B. Barrett, Scott Beattie +4 more

We report a measurement of the 5P3/2 excited-state lifetime using two-pulse photon echoes in Rb vapor. The measurement is precise to ∼1% and agrees with the best measurement of atomic lifetime in Rb. The results suggest that a measurement precise to ∼0.25% is possible through additional data acquisition and study of systematic effects. The experiment relies on short optical pulses generated from a cw laser using acousto-optic modulators. The excitation pulses are on resonance with the F=3-->F′=4 transition in Rb85 or the F=2-->F′=3 transition in Rb87. The resulting photon echo signal is detected using a heterodyne detection technique. The excited-state lifetime is determined by measuring the exponential decay of the echo intensity as a function of the time between the excitation pulses. We also present a study of the echo intensity as a function of excitation pulse area and compare the results to simulations based on optical Bloch equations. The simulations include the effects of spontaneous emission as well as spatial and temporal variations of the intensities of excitation pulses.

Lifetime measurements in the excited S states of K, Rb, and Cs by the cascade Hanle effect*

Basim R. Bulos, R. Gupta, W. Happer

The cascade Hanle-effect technique has been described in detail. It has been used to measure the radiative lifetimes of several excited S states in heavy alkali metal atoms. We obtained the following measurements (in nanoseconds): τ(K, 6 2S1/2) = 68 ± 9, τ(Rb, 7 2S1/2) = 91 ± 11, τ(Cs, 8 2S1/2) = 96 ± 14, and τ(Cs, 9 2S1/2) = 231 ± 35.

Radiative lifetimes of excited states of rubidium up to quantum number n=12

J Marek, Pamela N. Münster

The lifetimes of the Rb atomic levels n 2 S, n 2 P, n 2 D up to quantum number n=12 and of the 10, 11, 12 2 F states were measured using pulsed dye laser excitation and a single-photon counting technique. Population by superradiance was applied for the excitation of the certain levels. Some data were determined by the measurement in Rb-rare-gas systems. The present results have been compared with the theoretical and experimental data given by different authors.
