Hyperfine Paschen-Back regime realized in Rb nanocell
Résumé
A simple and efficient scheme based on a one-dimensional nanometric-thin cell filled with Rb and strong permanent ring magnets allows direct observation of the hyperfine Paschen-Back regime on the D1 line in the 0.5-0.7 T magnetic field. Experimental results are perfectly consistent with the theory. In particular, with σ+ laser excitation, the slopes of the B-field dependence of frequency shifts for all 10 individual transitions of 85;87Rb are the same and equal to 18.6 MHz∕mT. Possible applications for magnetometry with submicron spatial resolution and tunable atomic frequency references are discussed.
