Abstract

We develop a full quantum theory of transient-state electromagnetically induced transparency (EIT) in thevapor of three-level A-type atoms interacting with probe and coupling lasers. As applications of the full quantum theory,we show that transient-state EIT medium exhibits normal dispersion and find that group velocities of both coupling andprobe lasers are greatly reduced. It is shown that the group velocity of the probe laser in the transient-state EIT case isequal to that in the adiabatic EIT case and that the coupling laser group velocity in the transient-state EIT is generallyless than that in the adiabatic EIT.

Propagation of a laser pulse in a three-level cascade atomic medium under conditions of electromagnetically induced transparency

Nguyen Huy Bang, Minh Dong Hoang, Van Doai Le +2 more

We study the propagation dynamics of a single pair of probe and coupling laser pulses in a three-level cascade atomic medium by numerical solving the Maxwell-Bloch equations for atoms and fields. Influences of the pulse durations, intensity and pulse area of the coupling laser on the probe laser propagation are investigated. We found the conditions that the undistorted probe pulse in such medium, i.e., the EIT effect is established. Under EIT conditions, the ground state population is trapped in a dark state.

Investigation of Transient Properties of Electromagnetically Induced Transparency with a Strong Probe Laser

Xihua Yang, Zhenrong Sun, Li Hua +2 more

The transient properties of electromagnetically induced transparency (EIT) are studied with different probe pulse energies for the first time in the 3S 3P 3/2 4D ladder type three level system of sodium atom.The EIT effect would be reduced with the increase of the probe pulse energy. Theoretical calculation is carried out by solving the time dependent matrix equation. The experimental results agree well with the theoretical calculation.

Susceptibility and Group Velocity in a Fully Quantized Model For Electromagnetically Induced Transparency

Xiong-Jun Liu, Mo‐Lin Ge

We have developed a fully quantized model for EIT in which the decay rates are taken into account. In this model, the general form of the susceptibility and group velocity of the probe laser we obtained are operators. Their expectation value and fluctuation can be obtained on the Fock space. Furthermore the uncertainty of the group velocity under very weak intensity of the controlling laser and the uncertainty relation between the phase operator of coupling laser and the group velocity are approximately given. Considering the decay rates of various levels, we may analyze the probe laser near resonance in detail and calculate the fluctuation in both absorption and dispersion. We also discuss how the fully quantized model reduces to a semiclassical model when the mean photon numbers of the coupling laser is getting large.

Electromagnetically induced focusing in a Λ-type medium

Gong Shang-Qing, Zhizhan Xu, Pan Shao-hua

Electromagnetically induced transparency (EIT) in an inhomogenously broadened medium consisting of Λ-type three-level atoms has been analyzed. It is shown that the Λ system can induce a transparency of the medium when the probe laser and the coupling laser have the same frequency detunings (including zero). Across the EIT window, the radial variation of the strong coupling laser radiation may lead to electromagnetically induced focusing or defocusing of the weak probe laser at separate probe frequency detuning points.
