Abstract:
We report measurements of absolute transition frequencies and hyperfine coupling constants for the 8S(1/2), 9S(1/2), 7D(3/2), and 7D(5/2) states in Cs-133 vapor. The stepwise excitation through either the 6P(1/2) or 6P(3/2) intermediate state is performed directly with broadband laser light from a stabilized femtosecond laser optical-frequency comb. The laser beam is split, counterpropagated, and focused into a room-temperature Cs vapor cell. The repetition rate of the frequency comb is scanned and we detect the fluorescence on the 7P(1/2,3/2) -> 6S(1/2) branches of the decay of the excited states. The excitations to the different states are isolated by the introduction of narrow-bandwidth interference filters in the laser beam paths. Using a nonlinear least-squares method we find measurements of transition frequencies and hyperfine coupling constants that are in agreement with other recent measurements for the 8S state and provide improvement by 2 orders of magnitude over previously published results for the 9S and 7D states.
