Abstract
An effect of nonstationary amplification of the holographic recording in pure and transition-metal doped crystals of the sillenite type (Bi1 2SiO20, or BSO), irradiated in advance with light from the red or near -infrared spectrum, is investigated. This amplification can serve as a base for incoherent-to-coherent optical conversion. It is found that BSO crystals doped with iron and cobalt have a higher sensitivity and much wider spatial-frequency range, where the effect of the amplificat ion can be observed, compared with nondoped crystals.
