Photorefractive effect at 775 nm in LiNbO3 samples doped with Mg and Zr ions

What is it about?

We analyze the photorefractive effect present in doped LiNbO3 samples when irradiated with 775 nm light. This wavelength, not generally considered for photorefractivity experiments, is particularly relevant for the realization of nonlinear optical devices (in LiNbO3) for optical communication systems, such as wavelength converters, phase conjugators, etc...

Why is it important?

This is the first analysis dedicated to 775-nm photorefractivity. Results show, quite surprisingly, that the photorefractive effect is still very large (even using a so "long" wavelength), and its dynamics is very slow.
