Bichromatic Phase Control of Spontaneous Emissionin a Three-level V-type Atomic System

Abstract

Abstract: Spontaneous emission of a three－level V－type atom driven by a pair of bichromatic fields on the basis of density matrix equation and quantum regression theories are studied. The results show that the spontaneous emission depends strongly on the difference between the relative phases of two bichromatic fields, without depending on the respective phase or relative phase. Selective elimination of the spontaneous emission can be achieved simply by varying the relative phase difference.

Key words: spontaneous emission, density matrix equation, resonance fluorescence, quantum regression theorem
