A REVIEW OF PPLN CRYSTAL

The mechanism for GRIIRA arises from the generation of polarons from crystal defects for instance, Nb ions occupying Li ion web pages (known as antisite defects), and Fe ion impurities. Doping lithium niobate with MgO cuts down the onset of GRIIRA, mainly because it makes it possible for Mg ions to exchange the Nb antisite defects.Laser induced des
