Abstract :
Summary form only given. Periodic domain inversion by electric field application has become a mature technique to get unprecedented nonlinear interactions in congruent Z-cut lithium niobate (LN) crystals. Yet, it is currently limited by the high poling field (20 kV/mm) and the related probability of dielectric breakdown, prohibitive above 1 mm thick samples. In the present paper, periodic poling has been implemented starting from stoichiometric samples (SLN), obtained by top seeded solution growth from a potassium containing flux, and with a lithium content very close to 50% (UV absorption edge @20 cm/sup -1/; 302.2 nm).
