Phase Control of Luminescence Excited by Bichromatic Radiation

Russian Physics Journal Aims and scope

Abstract

A new method of phase control of photoprocesses based on the dependence of the power of luminescence excited by a bichromatic field on the phase shift between the monochromatic radiation components is suggested and analyzed. Calculations are carried out by the example of excitation of alkali metal atoms from the ground state to the first excited s-state with their subsequent luminescence as a consequence of spontaneous transitions to the intermediate p-level. The optimal parameters of the bichromatic field at which the effect is most pronounced are determined. A strong dependence of the luminescence phase modulation on the laser field intensity near the region of saturation of the excited transition is established. It is demonstrated that the wavelengths of bichromatic radiation and luminescence lie in the range easily accessible for an experiment.
