Abstract

The dependence of the polarization plane rotation angle in the BaF2 crystal on the intensity of the femtosecond laser radiation with 0.62 μm wavelength in the ω = ω + ω − ω process on cubical nonlinearity χ(3) is investigated. An anomalous increase in the efficiency of the cross-polarized radiation generation at I > 2 × 1012 W cm2 is observed for the first time. The 10% efficiency of the orthogonal component generation at the ∼3 × 1012 W cm2 intensity is obtained.
