摘要：

Permanent reversible diffraction gratings with refractive-index modulations of up to ≃10-4 and with a grating vector perpendicular to the polar axis are realized in LiNbO3:Cu crystals by making use of high temperature recording and charge compensation. The index changes do not result from light-induced space-charge fields and the linear electro-optic effect. They are linked to fixed high-contrast narrow-band absorption gratings of Cu+/Cu2+ ions via the Kramers–Kronig relations.
