Abstract

We have studied modification of the fluorescence spectra of a room-temperature atomic rubidium vapor in the region of 85^{85}Rb and 87^{87}Rb D2_2 line while changing the temporal rate of linear (triangular) scanning of laser radiation frequency. Increase of the ramping speed over certain value (\approx 106^6 MHz/s) results in essential modification of magnitudes of individual atomic transitions, different on rising and falling slopes, which characterize transition from a steady-state interaction regime to a transient one. Our experimental results are well consistent with the developed theoretical model. The obtained results can be used for determination of atomic system parameters such as ground-state relaxation rate. Possible follow-up actions on addressed control of atomic levels population is discussed.
