dc.description.abstract"The main objective of this thesis is to perform a numerical study of the generation and propagation of space optical solitons in a nonlocal medium as a realistic media. The nonlocality of the medium is considered numerically through different symmetric functions, where its width is considered as the degree of nonlocality. So, the propagation of arbitrary beam profile in a nonlocal medium is studied. Amazingly, by choosing appropriate beam-width, the intensity profile, can be confined in direction of propagation with small oscillation, called quasi-soliton. Some arbitrary initial beam profiles are investigated to propagate in nonlocal medium with appropriate initial beam-width, resulting in quasi-solitons (The quasi-soliton is a soliton-like beam that propagates similar to a soliton but demonstrates some oscillations in its intensity profile and beam-with). These quasi-solitons after some initial distance of propagation, reshape to a Gaussian profile, where their profiles are obtained analytically and are simulated for comparison with the final intensity profile. For this purpose, in this thesis, the propagation of the paraxial center of an intense beam in different media is investigated".
