Electro-optic and dielectric properties of photorefractive KNbO3

Two laser beams interfering in a photorefractive crystal ionize light absorbing impurities and produce two initially overlapping concentration gratings. These two gratings consist ...

Introduction: Idiopathic optic neuritis is an optic neuropathy with characteristics of optic nerve dysfunction that can be caused by various disorders of the optic nerve, including...

1. Introduction Photorefractive gratings are most often produced by illumination of an electro-optic crystal with laser light below the band gap and the absorbed photons induce pho...

Measurements on high quality samples of top-seeded-solution-grown crystal BaTiO3 have been performed in order to complete the set of data, which is necessary to describe the optic ...

ObjectiveThis retrospective study aimed to investigate the clinical features of optic neuritis associated with COVID-19 (COVID-19 ON), comparing them with neuromyelitis optica-asso...

We use a novel, nondegenerate, polarization-sensitive, transient-grating technique1 to monitor the picosecond dynamics of the photorefractive effect in undoped CdTe and InP:Fe at 9...

AbstractNanoscale potassium niobate (KNbO3) powders of orthorhombic structure were synthesized using the sol-gel method. The heat-treatment temperature of the gels had a pronounced...

Abstract Hereditary optic neuropathies are a group of disorders characterized by optic nerve damage in which the underlying cause is heritable. Optic atrophy is a cl...
