Double resonance optical pumping spectroscopy has an outstanding advantage of high signal-to-noise ratio, thus having potential applications in precision measurement. With the counter propagated 780 nm and 776 nm laser beams acting on a rubidium vapor cell, the high resolution spectrum of 5 S 1/2 − 5 P 3/2 − 5 D 5/2 ladder-type transition of 87 Rb atoms is obtained by monitoring the population of the 5 S 1/2 ground state. The dependence of the spectroscopy lineshape on the probe and coupling fields are comprehensively studied in theory and experiment. This research is helpful for measurement of fundamental physical constants by high resolution spectroscopy.Double resonance optical pumping spectroscopy has an outstanding advantage of high signal-to-noise ratio, thus having potential applications in precision measurement.

Optical double-resonance cooled-atom spectroscopy

Thomas H. Loftus, Jason R. Bochinski, THOMAS W. MOSSBERG

We demonstrate that laser cooling, combined with $V$ -scheme optical double-resonance spectroscopy, provides a sensitive means to measure isotope shifts and hyperfine splittings. Our technique is illustrated using the 398.8-nm ${(6s}^{2}{)}^{1}{S}_{0}{\ensuremath{-}(6s6p)}^{1}{P}_{1}$ and 555.6-nm ${(6s}^{2}{)}^{1}{S}_{0}{\ensuremath{-}(6s6p)}^{3}{P}_{1}$ transitions in a neutral ytterbium atomic beam having natural isotopic composition. With a precision comparable to existing approaches, our unique method has enabled the most complete single-technique survey to date of the ${}^{1}{S}_{0}{\ensuremath{-}}^{1}{P}_{1}$ isotope shifts and hyperfine splittings.We demonstrate that laser cooling, combined with $V$-scheme optical double-resonance spectroscopy, provides a sensitive means to measure isotope shifts and hyperfine splittings.
