Abstract :
We observe space dispersive, second harmonic green generations from a 2D QPM-periodically poled LiNbO3 pumped by a Nd:YAG laser. The angular-tuning and phase-matching temperature analyses reveals a simultaneous quasi-phase-matching mechanism up to five reciprocal lattice vectors in the 2D χ(2) nonlinear photonic structure of tetragonal symmetry.
