Prescription for long-lifetime, high-diffraction-efficiency fixed holograms in Fe-doped LiNbO₃

Abstract

A prescription for a material preparation and fixing technique is presented that permits a thermally fixed hologram to be recorded in Fe-doped LiNbO₃ with high diffraction efficiency and a long lifetime. In particular, a hologram with a fixed refractive-index modulation of nearly ${10}^{-3}$ and a 100-year lifetime at room temperature is predicted.
