Based on nonlinear Talbot effect, we propose an acousto-optic tunable second-harmonic (SH) array in a one-dimensional periodically poled LiNbO3 (PPLN) crystal. The SH array is the self-imaging of chi((2)) in the PPLN crystal. By applying an acoustic wave, we can tune the period, the distribution, and even the dimension of the array. Such a phenomenon has potential applications in tunable high-resolution Talbot illuminators, beam shapers, and image processing. (C) 2012 Optical Society of America
