Abstract

We report experimental observation of velocity-selective resonances in the Doppler-broadened probe absorption spectra of ⁸⁵Rb and ⁸⁷Rb D ₂ transitions in the presence of a strong co-propagating pump laser locked to a frequency within the Doppler profile of the transition. The set of three dips having the separation of allowed hyperfine transitions move along the Doppler profile while the pump laser frequency is tuned. This indicates a resonance between the pump laser frequency and the velocity shifted probe laser frequency.
