摘要
The new mechanism for obtaining a nonlinear phase shift has been proposed and the schemes are described for its implementation. As it is shown, the interference of two waves with intensity-dependent amplitude ratio coming from the second harmonic generation should produce the nonlinear phase shift. The sign and amount of nonlinear distortion of a beam wavefront is dependent of the relative phase of the waves that is introduced by the phase element. Calculated value of exceeds that connected with cascaded quadratic nonlinearity, at the same conditions.
