The role of defects in the photorefractive effect is known in principle: their photoionization in
the brighter regions of a photorefractive crystal, illuminated by an inhomogeneous light …

The formation of self-confined beams using pyroelectric effect is numerically and
experimentally studied in photorefractive LiNbO3. For a given crystal temperature change …

以双中心模型为基础, 理论研究了LiNbO3: Fe: Mn 晶体在稳态情况下的非挥发双光双步全息
存储性能. 采用数值方法, 通过比较深(Mn^ 2+/Mn^ 3+), 浅(Fe^ 2+/Fe^ 3+) 能级之间所有可能的 …

We present the experimental demonstration of a self-trapped optical beam bending in a
photorefractive Fe-doped lithium niobate (LN: Fe) crystal controlled by the pyroelectric effect …

We observe ultraviolet-light-induced absorption changes in spectral regions from the near-
ultraviolet to the near-infrared in as-grown LiNbO 3: Mg. Such a broad light-induced …

Light-induced heating under high-average-power laser is investigated in LiNbO_3-type
crystals in green second-harmonic generation. A rate-equation based on the kinetics of …

Control over magnetic properties by optical stimulation is not only interesting from the
physics point of view, but also important for practical applications such as magneto-optical …

Z-cut MgO heavily codoped (6 mol%) Er (0.4 mol%): Li Nb O 3 crystals were thermally
treated at 1110 and 1120 C over 100, 120, and 220 h using vapor transport equilibration …

An interferometric Mach-Zehnder technique very recently developed has been applied to
measure photorefractive index changes in different types of z-cut proton-exchanged planar …

The influence of composition on the photorefractive effect in pure LiNbO3 crystals at low light
intensity was investigated. The experimental results indicate that different defects dominate …
