Mechanisms of holographic recording in rubidium vapor close to resonance
N. Korneev, Olena Benavides
Abstract
We investigate the nonlinear refraction and absorption related to holographic writing in rubidium vapor at resonance with 87Rb D2 transition. The numerical model based on time-dependent density matrix formalism is used. The theory adequately describes nonlinear optical rotation and absorption at light intensities in the 0.1-30 mW/cm2 range. The basic configurations for obtaining amplitude and phase gratings for nearly equal frequencies of writing beams are investigated experimentally, and the writing time is estimated.
