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 ...

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 ...

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...

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...

In a photorefractive experiment the space-charge grating is built-up along a certain axis and it modulates the refractive indices via the linear electro-optic (EO) effect. In many ...

Abstract Purpose: To report a case of anterior ischemic optic neuropathy (AION) following COVID-19 vaccination and provide a systematic review of all published cases of op...

Objective: To compare the efficacy of electro-acupuncture with that of sham electro-acupuncture for auditory hallucinations in patients with schizophrenia partially responsive or n...
