چکیده
Inversionless gain is observed in a V-type inhomogeneously broadened system without introducing any incoherent pumping and only by changing the collisional dephasing decay rate. In this system sub-Doppler linewidth is achieved with off-resonance pump detuning.

Controlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
متن کاملDouble Electromagnetically Induced Transparency in a Tripod-type Atom System
The electromagnetically induced transparency (EIT) phenomenon in a four level atomic system with tripod configuration is studied. The results show that this configuration is equivalent to the combination of two single three-level Λ configurations, which, under certain conditions, results in the so-called double-EIT (DEIT) phenomenon. The properties of the double transparency windows for DEIT ar...
متن کاملElectromagnetically induced spatial nonlinear dispersion of four-wave mixing
Spatial displacements of the probe and generated four-wave mixing beams are observed in a three-level V-type, as well as a two-level atomic system near resonance. The observed spatial shift curves reflect the typical enhanced cross-Kerr nonlinear dispersion properties in the electromagnetically induced transparency EIT systems. The spatial beam displacements are controlled by the strong control...
متن کاملControlling optical bistability in a three-level atomic system
We have experimentally studied the optical bistable behavior in an optical ring cavity filled with a collection of three-level L-type rubidium atoms, interacting with two collinearly propagating laser beams. The bistability so observed is very sensitive to the induced atomic coherence in this electromagnetically induced transparency system or consequently to the altered nonlinearity in the syst...
متن کاملElectromagnetically induced grating: Homogeneously broadened medium
A strong coupling standing wave, interacting with three-level L-type ~or ladder-type! atoms, can diffract a weak probe field ~propagating along a direction normal to the standing wave! into high-order diffractions, a phenomenon which we name electromagnetically induced grating ~EIG!. We develop in this work a theory for studying EIG in a homogeneously broadened medium consisting of three-level ...
