Propagation of an array of four Gaussian light beams in a SBN crystal

This paper presents a theoretical research on the propagation of an array of four Gaussian light beams in a SBN crystal. Results show that quasi-soliton regime of array propagation is achieved for values of E 0 >1000 V/cm. Finally, theoretical results are in qualitative agreement with the experimental results obtained by authors from Institute of Applied Optics, University Jena.
