Abstract
We theoretically investigate the evolution of optical beams in nonlocal nonlinear media of gradual nonlocality, which is governed by the nonlocal nonlinear Schrödinger equation with variable coefficient. With the variational approach, the evolution equation of beam width is derived. When the characteristic length of response function gradually changes with any functional forms, beams can exhibit a kind of adiabatic evolution. The variational results are well confirmed by numerical simulations.
