Abstract

Second-harmonic generation in a photorefractive crystal is investigated. It is shown that a fundamental wave that is not in the photorefractive regime can be locked onto a second harmonic, creating a photorefractive effect. This locked state can be manipulated by another harmonic beam to suggest some scanning and routing applications. An interesting split-field method is used to account for the soliton dynamics in a $(1+1)D$ configuration. Numerical simulations are used to confirm analytical results for this case.
