Abstract :
In a three-level lambda system, a destructive interference between excitation pathways at laser excitation can provide the resonant reduction of fluorescence and absorption (“dark resonance”). The dark resonances in rubidium vapor excited by a femtosecond laser or laser with frequency shifted feedback have been studied theoretically and experimentally.
