Abstract

A photorefractive crystal of the sillenite family in a two-wave mixing experiment is used as a fundamental component in a negative feedback system for stabilizing a holographic setup. The behavior of such a stabilization system is theoretically analyzed, and the advantages and limitations of using a real-time nonpermanent recording material (photorefractive crystal) are discussed. We present experimental results using a Bi₁₂TiO₂₀ crystal, compare actual and predicted performances, and discuss the optimization of relevant parameters for better performance of the whole stabilizing system. Theoretical analysis and experimental results show this system to have interesting perspectives for further development.
