title: Shifting bright spatial solitons in LiNbO3.
abstract: We observe spatial bright solitons in a transversely shifting LiNbO3 crystal. In this scheme, the photovoltaic nonlinearity in LiNbO3 can be switched from self-defocusing to self-focusing by continuous shifting of the beam. Moreover, the shifting velocity has a strong influence on the wave shape of the bright spatial solitons.
