Dressed spontaneous parametric the four-wave mixing process in Pr³⁺:YSO crystal

Abstract

We investigate fluorescence (FL) and spontaneous parametric four-wave mixing (SP-FWM) signals in V-, Λ- and N-type energy level systems by changing the frequency detuning or power of the dressing field in Pr3+ doped Y2SiO5 at 77 K. The lifetime of the two kinds of signals has been calculated, and the desired experimental results have been obtained. We successfully control the intensity and lifetime of fluorescence and SP-FWM signals by changing the power or frequency detuning of the dressing field. The research has potential applications in optical switches and all optical communication.
