Inhibition and Enhancement of Two Photon Absorption.
TLDR
Possibility of considerable enhancement of two photon absorption even in the presence of Doppler broadening is demonstrated.Abstract:
The possibility of transparency against two photon absorption is predicted. Detailed absorption profiles under different conditions of the control laser are given. A novel explanation of the absorption minimum is given in terms of the two photon Fermi golden rule and the dressed states. Possibility of considerable enhancement of two photon absorption even in the presence of Doppler broadening is demonstrated.read more

TL;DR: A hyper-Raman scheme for generation of coherent light in a five-level atomic system based on electromagnetically induced transparency (EIT) is proposed and it is shown that EIT suppresses linear and nonlinear photon absorption and enables the hyper- Raman process to proceed through real, near-resonant intermediate states.

Controlling the optical bistability and transmission coefficient in a four-level atomic medium
TL;DR: In this article, a four level atomic configuration is proposed for controlling the optical bistability and transmission coefficient with application on all-optical switching, where two circularly polarized components from a weak linearly-polarized probe beam are interacted separately by two transitions of this medium.
