Dark resonances in the field of frequency shifted feedback laser radiation
arXiv:1006.5595 · doi:10.1088/0953-4075/43/21/215402
Abstract
We present a theory of dark resonances in a fluorescence of a three-level atom gas interacting with a polychromatic field of a frequency shifted feedback (FSF) laser. We show that conditions for the resonance observation are optimal when the phase relations between the laser spectral components provide generation of a light pulses train. We study analytically the field broadening and the light shift of the resonances.
