Acousto-optic imaging is based on ultrasound modulation of multiply scattered light in thick
media. We experimentally demonstrate the possibility to perform a self-adaptive wavefront …

The photorefractive properties of Sn_2P_2S_6 crystals doped with Te and Sb in the near-
infrared wavelength range up to 1064 nm are reported. The main photorefractive …

Abstract Tin hypothiodiphosphate (Sn 2 P 2 S 6) is a very promising material for
photorefractive applications in the red and near-infrared wavelength range. The main …

Electron paramagnetic resonance (EPR) is used to identify the singly ionized charge state of
the Sn vacancy (⁠ V Sn−⁠) in single crystals of Sn 2 P 2 S 6 (often referred to as SPS) …

Quantum memories are inherently highly efficient and display low noise, making them
particularly suitable for the optical detection of ultrasound. Here, we use an atomic …

Single crystals of Sn 2 P 2 S 6 are both ferroelectric and photorefractive. Antimony (Sb) ions
are optically active in this material and play an important role in optimizing the …

In the present study, the electronic properties of both ferroelectric and paraelectric phases of
the Sn2P2S6 (SPS) chalcogenide crystal were investigated using first principles methods …

Enhanced photorefractive properties of tin hypothiodiphosphate (Sn_2P_2S_6) crystals as a
result of Bi do** are presented. These new crystals were obtained by the vapor-transport …

Unique holelike small polarons are produced at divalent cation sites by optical excitation at
low temperature in single crystals of Sn 2 P 2 S 6, a monoclinic ferroelectric and …

We demonstrated for what is the first time to our knowledge photorefractive two-wave mixing
in a bulk ferroelectric crystal using cw light at the telecommunication wavelength 1.55 μm. In …
