Research and technological institute of optical materials all-Russia scientific center "S.I.Vavilov State Optical Institute"

Research and development

The research and development activities of the Research and technological institute of optical materials all-Russia scientific center "S.I.Vavilov State Optical Institute" are concentrated in three research and production complexes: "Crystal", "Fibre", and "Glass".

The "Crystal" research and production complex carries out research studies and developments in three directions: activated crystalline materials, functional crystalline optical materials, and crystalline and polycrystalline media used in a wide spectral range (UV, visible range, infrared). This research and production complex carries out the following activities:

  • the growth of active optical elements from the crystals of gadolinium-scandium-aluminum garnet, double fluoride of yttrium – lithium with rare-earth elements, potassium-gadolinium tungstate activated by neodymium, barium nitrate, and nickel sulfate;
  • the production of leucosapphire blanks, calcium and barium fluoride, zinc selenide, and zinc selenide composite/zinc fluoride for through-passing optics in the UV, visible, and infrared ranges.

The "Fibre" research and production complex conducts experimental investigations in the following directions:

  • increasing the strength of photon-crystalline fibres;
  • designing optical guides for the production of Bragg gratings;
  • designing activated optical guides for fiber lasers;
  • designing optical guides in order to transfer powerful laser radiation;
  • research studies of the nonlinear-optical transformation of picosecond laser pulses in photon-crystalline fibers.

The "Glass" research and production complex conducts research and the development activities in three directions: optical glass, laser glass, and glass ceramics. In the "Optical glass" direction, the center continues its activities on the expansion of the catalogue of optical (more than 70 brands) and radiation-resistant (more than 60 brands) glass. The complex is developing new glass samples, inter alia, for fibre-optical products, including high temperature glass samples. For example, under the contract with Swarovski and Preciosa companies the specialists of the Research and technological institute of optical materials have successfully implemented to create color glass of a certain color scheme without harmful impurities.

The latest technology created in the direction "Laser glass" is light-absorbing glass synthesis technology for cladding disc active elements. The products created on the basis of this technology significantly exceed the characteristics of ordinary glass used for these purposes. The institute is manufacturing light-absorbing glass to fill an order by the Russian Nuclear Centre.

In the direction "Glass ceramics" the Research and technological institute of optical materials has developed optical glass with nanocrystals, which impart fundamentally new properties to the material. On the basis of these innovative products, the institute creates nanostructured materials for highly effective passive laser shutters, highly efficient diffusion reflectors, electro-optical glass-crystal elements, and gradient-indexes.
