This article describes a method of manufacturing a deep relief structure of variable depth, based on the chemical etching of glass modified by femtosecond laser radiation. An effective model of deep relief structure of variable depth, suitable for us

Photovoltaic and diffusion fields in nominally pure single crystals of stoichiometric composition (R = Li/Nb = 1) grown in the presence of 6 wt% K2O flux (LiNbO3 stoich. K2O) in nominally pure single crystals of complementary composition (LiNbO3), co

We have investigated the photorefractive (photoinduced) light scattering in lithium niobate single crystals: LiNbO3, LiNbO3:B, LiNbO3:Y(0.46 mas %), LiNbO3:Y(0.24):Mg(0.63 mas %), and LiNbO3:Ta(1.13):Mg(0.0109 mas %) that were grown from congruent me

A study of Raman spectra of lithium niobate single crystals: stoichiometric, ostensibly pure congruent LiNbO3, and congruent LiNbO3 containing admixture of yttrium is reported. Raman bands observed in spectra excited by visible laser radiation are th

In lithium niobate crystals doped with photorefractive iron and copper admixtures when lightening objects with broadband incoherent radiation one can observe typical orientation and polarized dependences of image contrast. The record does not realize

The article discusses the investigations into photorefractive light scattering (PRLS) in nominally pure single crystals of stoichiometric composition (Li/Nb = 1) grown from a melt with 58.6 mol % Li2O. It is demonstrated that the asymmetric pattern o

The changes of photorefractive light scattering (PRLS) in time and Raman spectra are investigated in congruous lithium niobate single crystals doped with “unphotorefractive” Gd3+ cations. The best cation concentration is determined for the bigges

Comparative studies are made of the photorefractive scattering of light in nonlinear single crystals of lithium niobate with congruent compositions (LiNbO3) doped with "photorefractive" Cu [0.015 mass %] and "nonphotorefractive" Zn [0.5 mass %] catio
