Abstract

High erase sensitivity is observed in heavily reduced crystals of Fe-doped LiNbO(3). Only 12 mJ/cm(2) of incident 4880-A radiation erases a hologram, nearly 3 orders of magnitude less energy than previously required. However, the maximum diffraction efficiency that can be reached in these crystals is substantially reduced. These results are shown to be consistent with an extremely low density of Fe(3+) ions. The crystals are resistant to optical scattering effects usually observed in Fe-doped LiNbO(3).

摘要

在深度还原的掺铁铌酸锂（LiNbO₃）晶体中观察到了高擦除灵敏度。仅12 mJ/cm²的4880埃入射辐射就能擦除全息图，所需能量比以前减少了近3个数量级。然而，这些晶体中所能达到的最大衍射效率大幅降低。结果表明，这些结果与极低密度的Fe³⁺离子是一致的。这些晶体对通常在掺铁铌酸锂中观察到的光学散射效应具有抗性。
