Which mechanism impairs holographic data storage using photorefractive crystals?

💡 Explanation

Photobleaching reduces the refractive index contrast within the crystal because the material undergoes irreversible chemical changes upon intense laser exposure, therefore recorded data degrades rather than being maintained, caused mainly by heating.
