Abstract

We present an analytical study of the time-dependent spectra of a three-level atom in the cascade configuration driven by two intense coherent fields and damped by a broadband squeezed vacuum. We have also studied the influence of the initial state preparation of the atom on the transient spectrum.

STEADY-STATE RESONANCE FLUORESCENCE FROM A THREE-LEVEL ATOM IN A SQUEEZED VACUUM

Guojian Yang, HUANG ZU-QIA, Gang Xiang Hu +1 more

Steady-state resonance fluorescence spectrum from a three-level atom driven coherently by two intense optical fields and damped by a squeezed vacuum is obtained, which shows the dependence of the spectrum strongly on the squeezing of the vacuum field and the phase difference between the squeezed component of the vacuum field and the driven fields.

Optical double resonance in a broadband squeezed vacuum

B. N. Jagatap, Q. V. Lawande, S. V. Lawande

We study fluorescence from a three-level atom in a cascade configuration driven by two coherent fields and damped by a broadband squeezed vacuum. Under the conditions that one or both of these fields are intense, a secular approximation is invoked to derive an analytical solution of the relevant master equation. When the two fields are in exact resonance with their respective transitions, expressions for the fluorescent spectra show a narrowing of the central peak for some specific values of the parameters of the squeezed vacuum and the phases between the driving fields and the squeezed vacuum. We also present analytical expressions for second-order intensity correlations. The inhibition of fluorescence in a squeezed vacuum is reflected in the quantum-jump-like behavior shown by these correlations.

Time-dependent spectrum of a strongly driven two-level atom in the squeezed vacuum

Amitabh Joshi, S. V. Lawande

The time-dependent fluorescence spectrum from a strongly driven two-level atom damped by a broadband-squeezed vacuum is obtained analytically using the counting-rate definition of Eberly and Wodkiewicz [J. Opt. Soc. Am. 67, 1252 (1977)] and employing the high-field approximation. The spectrum shows considerable modifications compared to the corresponding time-dependent spectrum in a normal vacuum. It is now dependent on the relative phase between the squeezed vacuum field and the coherent driving field. In particular, the time development of the central peak of the Mollow triplet (which is known to show a phase-dependent linewidth in the steady state) is discussed. The effects of detuning on the spectrum are also presented.

Resonance fluorescence spectra of three-level atoms in a squeezed vacuum

M. R. Ferguson, Z. Ficek, Bryan J. Dalton

The fluorescence field from one of the two allowed transitions in a three-level atom can sense squeezed fluctuations of a vacuum field coupled to the other transition. We examine the fluorescence spectra of strongly driven three-level atoms in \ensuremath{\Lambda}, V, and cascade configurations in which one of the two one-photon transitions is coupled to a finite-bandwidth squeezed vacuum field, when the bandwidth is much smaller than the difference in the atomic transition frequencies, though much larger than atomic decay rates and Rabi frequencies of the driving fields. The driving fields are on one-photon resonance, and the squeezed vacuum field is generated by a degenerate parameter oscillator. Details are only given for the \ensuremath{\Lambda} configuration. The extension to the V and cascade configurations is straightforward. We find that in all configurations the fluorescence spectra of the transition not coupled to the squeezed vacuum field are composed of five lines, one central and two pairs of sidebands, with intensities and widths strongly influenced by the squeezed vacuum field. However, only the central component and the outer sidebands exhibit a dependence on the squeezing phase. We also examine the fluorescence spectrum for the cascade configuration with a squeezed vacuum field on resonance with the two-photon transition between the ground and the most excited states and now generated by a nondegenerate parametric oscillator. In this case, where the squeezed vacuum field can be made coupled to both transitions, all spectral lines depend on the squeezing phase. The spectral features are explained in terms of the dressed-atom model of the system. We show that the coherent mixing of the atomic states by the strong driving fields modifies transition rates between the dressed states, which results in the selective phase dependence of the spectral features. \textcopyright{} 1996 The American Physical Society.

Time-dependent spectra of a strongly driven three-level atom

Arundhati S. Jayarao, S. V. Lawande, Richard D’Souza

Time-dependent features of the fluorescence radiation from a strongly driven three-level atom in a Raman configuration are studied applying the Eberly-W\'odkiewicz counting-rate definition of the spectrum. Using our earlier formalism, where we assume that one or both of the driving fields are intense, we obtain analytical expressions for the time-dependent fluorescence spectra. We have also studied the influence on the transient spectrum of the initial preparation of the atom in three different dressed states.
