摘要：

We analyze phase front shaping as a facilitator of sound-sound scattering measurements. At the primary fields level we present and review the lens mediation technique. We show the emerging possibility of measuring the effect with finite aperture beams. At the secondary field level quasi phase matching is analyzed as a potential mechanism to amplify the difference field generation. It is shown that significant gain can be achieved in experimental settings by inserting a nonlinear periodic structure in the intersection region of the beams.
