Popis:	Illumination of iron-doped lithium crystals (LiNbO3:Fe) with femtosecond pulses of 1.5μm wavelength results in large refractive index changes Δn in the order of 10−3. The sign of the refractive index changes depends on the polarization of the recording light. The results can be very useful for fabrication of tailored holographic components for telecommunication.
