Photoinduced Charge Transport in Optical Damage Resistant LiNbO3:Me (Me = Mg, Zn)

Abstract

Photoinduced charge transport in LiNbO3 is defined by presence of a Fe-like impurity, Fe2+ being the donor, Fe3+-the acceptor of electrons1. Two level scheme gives the linear dependence of photoconductivity (that is of inverse response 2 times of photorefraction) on the light intensity2.
