Motion of Localized Structures in the Case of Oblique Incidence of Radiation on a Nonlinear Interferometer

摘要

For wide-aperture interferometers filled with a medium with threshold nonlinearity and excited by external radiation, the transverse profile of the field of localized structures in the form of solitons and dissitons is found when taking spatial filtering into account. The drag coefficient determining the velocity of transverse motion of a single dissiton in the case of oblique incidence of external radiation is analytically calculated.
