Abstract
The purpose of this paper is twofold. First, we demonstrate optical fixing through two-step gated recording in a crystal of La3Ga5SiO14 doped with pra seodymium. Second, based on these experiments we suggest an excitation-reco mbination model for the photorefractive effect in the crystal and comment o n the nature of the intermediate level involved in the gated recording proc ess.
