Abstract
A process for reducing the poling field of congruent LiNbOand LiTaOcrystal-based nonlinear optical devices and for the production of domain structures with precise reproducibility of the main parameters by depositing a thin layer of a stoichiometric LiNbOfilm on the Z-face of a congruent LiNbOor LiTaOwafer. A new domain nucleation, evolution and stabilization process is provided to afford a uniform, short period domain superstructure for the conversion of near infra-red light to near ultraviolet, blue and green light.
