Abstract

We observe a narrow, isolated, two-photon absorption resonance in  87Rb for large one-photon detuning in the presence of a buffer gas. In the absence of a buffer gas, a standard Λ configuration of two laser frequencies gives rise to electromagnetically induced transparency (EIT) for all values of one-photon detuning throughout the inhomogeneously (Doppler) broadened line. However, when a buffer gas is added and the one-photon detuning is comparable to or greater than the Doppler width, an absorption resonance appears instead of the usual EIT resonance. We also observe a large negative group delay (≈-300 µs for a Gaussian pulse that propagates through the media with respect to a reference pulse not affected by the media), corresponding to a superluminal group velocity vg=-c/(3.6×106)=-84 m/s.

Fig. 1
Fig. 1

Three-level interaction scheme of three laser fields with  87Rb atoms. The long-lived coherence is created on the hyperfine split ground-state sublevels with a strong driving field Ed and a weak probe field Ep. A weak Stokes field Es is also present as a by-product of the generation of the probe field. Δ is the one-photon detuning of the drive and the probe lasers from their respective atomic transitions, and δ is the two-photon detuning, which is scanned.

Schematic of the experimental setup.

Transmission of the probe field as a function of two-photon detuning δ (measured in kilohertz) for various one-photon detunings Δ. (a)  87Rb cell with no buffer gas (vacuum) and (b)  87Rb cell with 30 Torr of Ne. The vertical scales are normalized in such a way that 0 corresponds to zero transmission and 1 corresponds to zero absorption (or total transparency). Experimental parameters: (a) T=66.4 °C, N=4.2×1011 cm-3; total power into cell 630 µW, out of cell 40 µW; 4.7-cm cell length. (b) T=67.7 °C, N=4.7×1011 cm-3; total power into cell ≈400 µW; 2.5-cm cell length.

Demonstration of negative pulse delayed time: (a) the probe field has a Gaussian temporal pulse shape and (b) the transmitted probe field showing a negative time delay before transmission. Experimental conditions are the same as for Fig. 3(b).

Calculated transmission of the probe field as a function of two-photon detuning δ (measured in kilohertz) for various one-photon detunings Δ: (a)  87Rb cell with no buffer gas (vacuum) and (b)  87Rb cell with 30 Torr of Ne. The vertical scales are arbitrary.
