Abstract

The 90-degree recording geometry has special advantages in suppressing holographic scattering and can be used for designing of compact volume grating components, but the main drawbacks are low diffraction efficiency and small sensitivity. In this paper, we optimized the components and oxidation states of LiNbO₃:Fe crystals for high diffraction efficiency during 90-degree holographic recording. The experimental results show that the samples with moderately doped components of Fe ions and high oxidation states have high diffraction efficiency.
