Effect of quantum interference processes on the angular distribution of the spontaneous radiation in the D line of alkali-metal vapors in a laser wave field

The resonance fluorescence of a degenerate V-type three-level atom in the f ield of an intense monochromatic wave with arbitrary polarization compositi on is investigated. The equations of motion, the general form of the radiat ion relaxation operator, and the analytical expressions for the angular dis tribution of the intensity of the spontaneous radiation from atoms, and the total intensity of the resonance fluorescence for such systems are obtaine d. The angular distribution of the spontaneous radiation from atoms for the D line of alkali-metal vapors is investigated. It is predicted theoretical ly that the intensity of the resonance fluorescence will decrease as the in tensity of the pump wave increases in observations in a direction of the el ectric field vector of the laser wave.
