Partially spatially incoherent photovoltaic spatial soliton
部分空间非相干光光伏空间孤子

A theory of spatially incoherent photovoltaic soliton of monochromatic light is presented. We find that the differential equation of spatially incoherent photovoltaic soliton is similar to that of spatially coherent photovoltaic soliton, and that the partially spatially incoherent photovoltaic spatial soliton can be approximately described by this theory. We have observed a partially spatially incoherent photovoltaic spatial bright soliton in a Cu:KNSBN crystal.
