We propose a method based on the electromagnetically induced transparency (EIT) phenomenon for the detection of molecules which exist as a small minority in the presence of a majority of absorbers. The EIT effect we employ effectively eliminates the absorption of the majority species in the spectral region where it overlaps with the absorption of the minority species. The method can also be used to enhance local-modes transitions which overlap spectrally with a background of other local-modes…

Electromagnetically induced transparency in a dipolar molecular system with Laguerre–Gaussian mode
Electromagnetically induced transparency (EIT) in a molecular three-level system with permanent dipole moments (PDMs) and the control beam in Laguerre–Gaussian (LG) mode is investigated. The results
Overlapping resonances interference-induced transparency: the S0 → S2/S1 photoexcitation spectrum of pyrazine.
The phenomenon of "overlapping resonances interference-induced transparency" (ORIT) is introduced and studied in detail for the S(0) → S(2)/S(1) photoexcitation of cold pyrazine (C(4)H(4)N(2)). In
The effect of spherical metallic nanoparticles on electromagnetically induced transparency in spherical quantum dots
In this paper, electromagnetically induced transparency (EIT) is investigated in a GaAs spherical quantum dot (SQD) with central potential in presence of spherical metallic nanoparticle (SMNP).
Effect of light polarization and dimensions of Λ-type three level cylindrical quantum dot on electromagnetically induced transparency
Abstract In this paper, electromagnetically induced transparency (EIT) is investigated in a GaAs cylindrical quantum dot (QD) with parabolic potential. The Schrodinger equation is solved in effective
Simulating Coherent Multidimensional Spectroscopy of Nonadiabatic Molecular Processes: From the Infrared to the X-ray Regime.
A wide range of time-resolved spectroscopic techniques are surveyed, which span from the infrared to the X-ray regimes and can be used for probing the nonadiabatic dynamics in the vicinity of conical intersections.
Complete Quantum State Selectivity in Cold Molecular Beams Using Deflection-Resistant Dark States in a STIRAP Configuration.
This Letter proposes a method to achieve complete quantum state selectivity by producing resistance to electromagnetically induced deflection (EID) and that the state to be selected can be "dialed in" at will.
Forty years after the first dark resonance experiment: an overview of the COSMA project results
COSMA: Coherent Optics Sensors for Medical Application is an European Marie Curie Project running from 2012 to March 2016, with the participation of 10 teams from Armenia, Bulgaria, India, Israel,


Observation of electromagnetically induced transparency.
We report the first demonstration of a technique by which an optically thick medium may be rendered transparent. The transparency results from a destructive interference of two dressed states which

Electromagnetically induced transparency is a technique for eliminating the effect of a medium on a propagating beam of electromagnetic radiation. EIT may also be used, but under more limited
Electromagnetically induced transparency : Optics in coherent media
Coherent preparation by laser light of quantum states of atoms and molecules can lead to quantum interference in the amplitudes of optical transitions. In this way the optical properties of a medium
Electromagnetically induced absorption in a four-state system
A simple theoretical model describing the positive sign of subnatural-width absorption resonances in the recent experiment of Akulshin and co-workers [Phys. Rev. A 57, 2996 (1998)] is proposed. An
Observation of electromagnetically induced transparency in collisionally broadened lead vapor.
As stated in the text, Figs. 3 and 4 (transmission versus probe laser detuning) were taken at an energy of 10 nJ in a 0.5-mm-diam beam. We should have noted that when the probe energy is increased to
Identification of overlapping optical lines in molecular spectra by means of the coherent population trapping of quantum levels
A new method of molecular beam spectroscopy with the ultrahigh resolution is theoretically suggested. This method is based on the phenomenon of the coherent population trapping of molecular levels
Spectroscopy in Dense Coherent Media: Line Narrowing and Interference Effects
Spectroscopic properties of coherently prepared, optically dense atomic media are studied experimentally and analyzed theoretically. It is shown that in such media the power broadening of the

Electronic-resonance-enhanced coherent anti-Stokes Raman scattering of nitric oxide: saturation and Stark effects.
The ERE-CARS signal intensity is found to be much less sensitive to variations in the collisional dephasing rates under saturation conditions, and good agreement is observed between theory and experiment in terms of spectral peak locations and relative intensities.
