Abstract

The theoretical research of propagation of an array of four Gaussian light beams in a SBN crystal was based on the model published in [1], It was supposed that the light beams propagate in parallel to each other. Parameters of modeling were following: the thickness of the crystal was 20 mm, the radius of input beam was r₃₃=14 μm, the distance d between the centers of the beams and the external applied electric field E₀ was chosen as shown in the Figure. The dark intensity was equal to the maximal intensity of the input beam. The electro-optical coefficient r₃₃ was equal to 180 pm/V.
