Experimental Evidence of Internal Reflection of Two Dimensional Beam in Photorefractive (SBN61:Ce) Interface

摘要

We study the reflection of two-dimensional spatial solitons at the nonlinear interface between a saturable nonlinear medium (photorefractive crystal) and a linear medium. Our study places emphasis on determinign the experimental conditions under which the beam reflected by the nonlinear interface is still a spatial soliton.
