Purpose of the development: The invention relates to the field of nonlinear optics, in particular Dynamic holography, and may be used in diagnostic systems, laser scattering objects in the wavelength range 600-1000 nm.

Recommended application field: Can be used in the physical and medical research laboratories and institutes in the development of diagnostic methods and the development of biological methods of optical information processing, as well as in the performance of basic and applied research.

Advantages over analogues: Currently achieved parameters that significantly exceed the value of such well-known foreign analogs in the wavelength range 630-852 nm. A preliminary study on the model of the device confirm the perspective of the application of these materials.

The development stage readiness: Ready for application

Technical and economic effect: Use of the material allows for optical sensing of inhomogeneities in scattering media (in particular in biological tissues) in the spectral region of "therapeutic window" of transparency, ie minimum absorption of hemoglobin. Based on it can be implemented promising methods for preliminary diagnosis of tumors in living tissue.

Description of the development:
()
The object of the invention is to provide a photorefractive material, effective in 600-1000nm spectrum, which is characterized by a sufficiently high coefficient of two-wave mixing and small (on the order of milliseconds) the time of formation of dynamic holograms based on doped single crystals Sn2P2S6. Using the methods of dynamic holography based photorefractive material parameters enables us to strengthen the weak optical signals near infrared range and highlight the desired signal by a significant dispersion. The technology of obtaining material and postgrowth processing, demonstrated its efficacy in the model of the device.
