Prescription for long-lifetime, high-diffraction-efficiency fixed holograms in Fe-doped LiNbO(3).
A prescription for a material preparation and fixing technique is presented that permits a thermally fixed hologram to be recorded in Fe-doped LiNbO(3) 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.
