Superluminal light propagation in a bi-chromatically Raman-driven and Doppler-broadened N-type 4-level atomic system
Bakht Amin Bacha, Fazal Ghafoor, Iftikhar Ahmad
We investigate the behavior of fast light pulse propagation in an N-type Doppler-broadened 4-level atomic system using double Raman gain processes. This system displays novel and i…
Avoidance of instability of a superluminal Gaussian light pulse via control of nonlinear coherence Kerr effect in a gain-assisted medium
Bakht Amin Bacha, Fazal Ghafoor
We investigate nonlinear Kerr-induced coherence effect on a superluminal probing light pulse in a gain-assisted N-type 4-level atomic system via an intense monochromatic laser fiel…
Hole-burning in an Autler-Townes doublet and in superluminal (subluminal) Electromagnetically induced transparency of a light pulse via a joint nonlinear coherent Kerr effect and Doppler broadening
Bakhtt A Bacha, Fazal Ghafoor, Iftikhar Ahmad
We investigate the behavior of light pulse propagation in a 4-level double Lambda atomic system under condition of electromagnetically induced transparency. The Fano type interfere…
An alternative realization of spontaneous emission cancelation via Field Generated Coherence (FGC)
Fazal Ghafoor
In contrast to the traditional Spontaneous Generated Coherence (SGC), Field Generated Coherence (FGC)-based atomic scheme is presented for spontaneous emission cancellation. It is…
Autler-Townes multiplet spectroscopy
Fazal Ghafoor
We extend the concepts of the Autler-Townes doublet and triplet spectroscopy to quartuplet, quintuplet and suggest linkages in sodium atom in which to display these spectra. We exp…
