Saturated absorption spectroscopy: elimination of crossover resonances by use of a nanocell

A. Sargsyan, D. Sarkisyan, A. Papoyan +6

It is demonstrated that velocity selective optical pumping/saturation resonances of reduced absorption in a Rb vapor nanocell with thickness \textit{L=} $\lambda$, 2$\lambda$, and 3$\lambda$ (resona…
