Spatio-temporal enhancement of Raman-induced frequency shifts in graded-index multimode fibers

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 Schr ö dinger equation that includes the spatial self-imaging effects through a periodically ...
