Lifetime Autler-Townes Splitting of Dressed Multi-Order Fluorescence in Pr3+:YSO

Abstract

HIGHLIGHTS• We observed Autler-Townes splitting of single peak into two and three peaks in two-level, and three-level systems, respectively. • We reported primary and secondary Autler-Townes splitting are caused by double cascaded dressing in time domain.• We observed Autler-Townes splitting of multi-order fluorescence in time domain is more obvious than that of in spectral domain.
