We report the direct recording of electron-based photorefractive hologram in nominally
undoped Bi 12 TiO 20 crystals using 780 nm wavelength light without pre-exposure or any …

Single crystals of Bi12SiO20 were grown from the melt by the Czochralski technique. The
critical crystal diameter dc= 10 mm and the critical rate of rotation ωc= 20 rpm were …

This paper consists of two parts. The first contains a short review of the main characteristics
and holographic phenomena typical of sillenites, and the second part is devoted to new …

We report on a digital system for the stabilization of an interference pattern of light fringes.
This system uses a Raspberry Pi computer to operate a continuously stabilized setup and …

This work presents a holographic method based on active feedback techniques for
determining the sign of the dominant charge carriers in photorefractive materials. A two-step …

Abstract. A technique based on self-diffraction of the recording laser beams, one of which is
phase modulated, is used for the estimation of the limiting trap concentration in …

將光折變晶體應用在全像光學儲存系統中作為儲存媒體是一個很有潛力的資訊儲存技術,
如何達成長時間的資訊儲存則是此技術中一個主要的議題, 使用雙波長寫入的光定影技術是一個 …

We report the use of Lloyd's mirror interferometer for holographic recording in
photorefractive material. The experimental results show that perturbations in the diffraction …

The steady-state exact solution for the higher harmonic gratings that synthesize the space-
charge field is derived without restrictions within an electron-hole transport model which …

The low-temperature dynamic properties of photorefractive gratings in cobalt-doped
potassium–strontium–sodium–barium–niobate crystals are reported. At low temperatures …
