摘要：
The coupling of two mutually incoherent. optical beams with the same polarization and wavelength in two-photon photorefractive crystals is studied. It is shown that incoherently coupled dark-dark, bright-bright, and bright-dark soliton pairs are possible due to two-photon photorefractive effect.
