Abstract
We report an experimental comparison of three-photon-absorption resonances (N-resonances) for the and optical transitions of thermal vapor. We find that the N-resonance has better contrast, a broader linewidth, and a more symmetric line shape than the N-resonance. Taken together, these factors imply superior performance for frequency standards operating on alkali N-resonances, in contrast with coherent population trapping resonances, for which the transition provides poorer frequency standard performance than the transition.
