Abstract

Reported studies of recording information were made with a number of LiNbO₃ compositions: stoichiometric and congruent single crystals. The present study shows that recording is possible in pure LiNbO₃ single crystals and in single crystals containing inactive cation dopants. Recording in stoichiometric crystals is likely possible because of a considerable amount of electrons localised in shallow traps. Absence of recorded information in pure congruent crystals were observed.
