Abstract :
The observation of multiple-order Raman-Nath nonlinear diffraction of beam by a one-dimensional nonlinear chi(2) grating is reported . The observed second harmonic (SH) diffraction patterns in a one dimensional grating is seen in a LiNbO3 crystal. The observed effect can find application as non-distractive testing of the poling structure and in second harmonic nonlinear microscopy.
