Abstract

A pronounced photorefractive effect in La3Ga5SiO14-Pr3+ crystal has been revealed. This is the first observation of the photorefraction caused by a bulk photovoltaic effect in photosensitive piezoelectrics. Owing to symmetry pecularities of a bulk photovoltaic effect in trigonal La3Ga5Si014, a value and a sign of the photorefraction depend on the orientation of an inducing light polarization vector. Experimental photorefraction data are in good accord with phenomenological description. The discovered phenomenon may lead to advanced application of La3Ga5Si014 crystals in photorefractive recording and holographic adaptive optics.
