title: High-contrast and narrow-linewidth resonant profile for continuous operation atomic clock.
abstract: We report a high-contrast and narrow-linewidth resonant line profile by measuring the magneto-optical rotation of the transmitted light in a forward-scattering arrangement. We also report the splitting of the transmitted line profile at a strong microwave excitation. This profile may provide a good competitive scheme for the passive Rb frequency standard.
