Experimental study of the self-deflection of a light beam in a photorefractive crystal exposed to an external alternating electric field

We have experimentally studied the propagation of an intensity-modulated light beam in a Ba 2 NaNb 5 O 15 photorefractive crystal exposed to an external alternating sinusoidal electric field. The dependence of the extent of beam self-focusing on the applied field amplitude is determined. The possibi...

Description
Summary:We have experimentally studied the propagation of an intensity-modulated light beam in a Ba 2 NaNb 5 O 15 photorefractive crystal exposed to an external alternating sinusoidal electric field. The dependence of the extent of beam self-focusing on the applied field amplitude is determined. The possibility of soliton formation under such conditions is demonstrated.
