Effects of finite bandwidth on the resonance fluorescence spectrum inside of a cavity

Abstract

We have considered the steady-state resonance fluorescence spectrum for a beam of two-level atoms, interacting with a strong driving field with a finite bandwidth inside a cavity. The competitive effects of cavity losses and the finite bandwidth of the intense driving laser beam on the resonance fluorescence spectrum have been discussed. Our results show that the usual three-peaked resonance fluorescence spectrum starts merging back into the central peak as the bandwidth of the driving field increases. Moreover, the asymmetry introduced by the detuning of the driving field having a finite bandwidth is also affected by the cavity losses.PACS number(s): 42.50.Lc, 42.50.Ar

Entanglement of three-mode light via six-wave mixing in a four-level Y-type atomic system

“…However, ordinary lasers have definite linewidths. Here, we first discuss the effect of the laser linewidth [56][57][58][59] for the present scheme. The Rabi frequencies l (l = 1, 2, 3) have fluctuating phases ψ l (t) (l = 1, 2, 3), which are characterized by the random force d dt ψ l (t) = f l (t) with zero averages and white noise correlations…”

Competitive stochastic noises in coherently driven two-level atoms and quantum interference

“…Another typical example of a stochastic perturbation of a system of coherently driven two-level atoms is the phase noise of the laser field. The effect of the linewidth of the driving laser on the spectrum has been widely investigated in the literature [29,30,31,32,33], but no quantum interference effects have been found. In reference [34], however, it is suggested that an interference phenomenon similar to that induced by collisional noise can appear due to a large phase noise of the driving laser field.…”
