Abstract: We explore the concept that the Raman process can be used as an effective way for transfer of optical vortices. In a four-level atomic system, two strong fields are applied to form a Λ-type subsystem… read more here.

DOI: 10.1364/ol.44.002637
Abstract: We investigate the impact of intrapulse Raman scattering and third-order dispersion on the propagation of a pulsed optical beam inside graded-index (GRIN) fibers by solving an effective nonlinear Schrodinger equation that includes the spatial self-imaging… read more here.
