| Abstract: | The coupling of two mutually incoherent optical beams with the same polarization and wavelength in two-photon cen-trosymmetric photorefractive crystals is studied. The result shows that incoherently coupled dark-dark, bright-bright and bright-dark screening soliton pairs in centrosymmetric photorefractive crystals are possible due to two-photon photorefractive effect. |
| Keywords: | nonlinear optics two-photon photorefractive effect centrosymmetric photorefractive material spatial optical solitons |
