Abstract

Second-harmonic generation (SHG) by quasi-phase-matching (QPM) in periodically domain-inverted structures offers the advantages of shorter wavelength accessibility and high conversion efficiency. Blue-light generation in domain- inverted LiNbO3 has recently been studied. 1 However, photorefractive damage is known to occur in this material, possibly limiting its potential at higher powers. On the other hand, LiTaO3 is reported to be more resistant to photorefractive damage,2 and it also has the advantage of a low-temperature process. Ferroelectric inversion layers have been reported,3 but periodic domain-inversion is necessary for QPM-SHG.
