Abstract:

In order to obtain Temperature and intensity effect on self-deflection of Gaussian beam in an unbiased serial photorefractive crystal circuit .When a Gaussian beam and a dark solution beam are incident on the PR crystal, respectively, then effectcs of changing the temperature and intensity of dark solitons of the on the self-deflection of the match of Gaussian beam with one bright solitons are discussed by numerical calculations.The result shows that the bending distance of the gauss beam centre increases with temperature rise, decreases as temperature continuously rises. All the results have great value to the engineering realization of the optical-control optical and thermo-control optical devices.
