Аннотация:The dependence of the polarization plane rotation angle in the BaF2 crystal on the intensity of the femtosecond laser radiation with 0.62um wavelength in the w=w+w-w process on cubical nonlinearity is investigated. An anomalous increase in the efficiency of the cross-polarized radiation generation at I> 2×10^12W/cm2 is observed for the first time. The 10% efficiency of the orthogonal component generation at the ~3×10^12W/cm2 intensity is obtained.
