Abstract
Polarization-dressed time-delayed fluorescence (FL) processes in Pr3+:YSO crystal are investigated experimentally. By changing the polarization of the incident beam, the double-dressing effect and the time delay of the second- and fourth-order FL processes can be controlled. Furthermore, the total evolution of the temporal FL signals with different incident beam intensities is observed. The two split peaks of FL in time domain are suppressed by the polarized dressing field. The switch of the suppressed dip and the enhanced peak at different time positions has also been studied. In addition, the evolution of the FL spectral signal at the adiabatic population transition stage, the build time, and the decay time of temporal FL signal with varied incident beam polarizations are also investigated. Such results can find potential applications in all-optical communication on photonic chips.
