Buffer-gas-induced absorption resonances in Rb vapor
Additional Document Info
Transformation of the electromagnetically induced transparency (EIT) resonance into an absorption resonance in Rb vapor was investigated. The transformation occurs as one-photon detuning of the coupling fields is varied. It was found that no such absorption resonance occurs in the absence of a buffer gas. It was also found that the width of the absorption resonance is several times smaller than the width of the EIT resonance.
