Abstract
We demonstrate a narrowband optical filter which operates on the 52S1/2 to
52P3/2 transition at 780 nm in rubidium vapor based on optical-pumping-induced
dichroism combined with Faraday anomalous dispersion effects. Its peak transmission
is 18.4(2)% at the 52S1/2, F = 2 to 52P3/2, F ' = 1, 3 crossover transition, whereas
at the 52S1/2, F = 2 to 52P3/2, F ' = 2, 3 crossover transition the transmission is
18.6(2)%. Both transitions have a bandwidth (full-width at half-maximum of peak
transmission) as narrow as 24.5(8) MHz, which is remarkably improved compared with
the narrowest bandwidth as we know. This technique can also be applied to other
alkali atoms.
