Abstract :
Summary form only given.In recent years there has been increasing interest in the use of quasi-phase-matched periodically poled lithium niobate (PPLN) for a variety of frequency conversion applications. We investigate the influence of of MgO doping on the green-induced infrared absorption, photorefraction, and ferroelectric domain nature in near stoichiometric LiNbO/sub 3/, and MgO doped near-stoichiometric LiNbO/sub 3/ are expected to show much improved nonlinear properties since they have considerably reduced photorefraction, and ferroelectric domain switching compared to congruent crystals.
