Multiorder nonlinear diffraction in frequency doubling processes

Saltiel, Solomon M.; Neshev, Dragomir N.; Krolikowski, Wieslaw; Arie, Ady; Bang, Ole; Kivshar, Yuri S.


We analyze experimentally light scattering from 2 nonlinear gratings and observe two types of second-harmonic frequency-scattering processes. The first process is identified as Raman–Nath type nonlinear diffraction that is explained by applying only transverse phase-matching conditions. The angular position of this type of diffraction is defined by the ratio of the second-harmonic wavelength and the grating period. In contrast, the second type of nonlinear scattering process is explained...[Show more]
