Observation of Continuum-Continuum Autler-Townes Splitting

Continuum-Continuum Autler-Townes Splitting in Calcium

“…Above 1 0 ' l W/cm2, the fine structure manifests itself only in the splitting. This confirms our previous calculation [6] and is further illustrated in Fig. 5 which shows the peak energies versus intensity for the "on resonance" case.…”

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

“…The two peaks in the FL spectral signal (Figure 3f5) can be seen clearly while central peak is very small, which cannot seen because of near double resonance dressing at 1 ∼ 2 ∼ 0 [12]. Thus, the time domain ( Figure 3A) AT-splitting is more sensitive than spectral ( Figure 3F) [10]. Figure 4A shows the variation of composite FL signal intensity at 2 = 0 in the time domain by changing QWP polarization of E b (θ 3 ) from circular to linear polarization states (bottom to top) and scanning E a .…”

“…The polarization dependences of four-wave mixing (FWM) and the enhanced FWM have been studied [7,8]. The atomic Autler-Townes (AT) splitting was first observed on an rf transition [9] and then in calcium atoms [10]. Here we study AT-splitting of fluorescence (FL) in time domain, which exhibit several applications in all-optical communication and optical information processing on photonic chip.…”

Observation of Autler–Townes Splitting of Second-Order Fluorescence in Pr3+:YSO

“…2 Such an AT splitting effect was also observed in four-wave mixing (FWM) process in two-level systems. 3 Besides, progresses related to atomic coherence 4 in solid-state materials have provided bases for potential applications, such as optical storage, 5 optical velocity reduction and reversible storage of double light pulses, 6 and controllable erasing of optically stored information.…”
