OREANDA-NEWS. Shvabe Holding has opened new opportunities for development of laser instrument engineering, having generated and patented the technology of unique crystal growing.

In order to improve the efficiency of generation in an yttrium-aluminum flashlamp-pumped laser with a wavelength of 1.064 microns, the specialists of one of Shvabe Holding companies - Polyus Research Institute of M.F.Stelmakh - have not only developed a new technology for crystal growing, but have also created a unique active element. The novelty is a crystal of yttrium-aluminum garnet alloyed by neodymium with peripheral absorbing layer which provides suppression of various effects (superfluorescence, parasitic modes) prone to reduce the power of laser irradiance.

"This achievement has become possible due to procurement of a modern installation for crystal growing within the Federal Targeted Program Development of the Electronic Component Base and Radio Electronics for 2008-2015. Today we have all the necessary equipment for production of hardware components for any solid-state lasers, for creation of various crystals with improved characteristics. This opens up entirely new possibilities for developers of laser equipment, namely, the improvement of laser irradiance efficiency", said Yuri Golyaev, Interim General Director of Polyus Research Institute of M.F.Stelmakh.

Currently, the company continues to complete work on manufacture of crystals for the new technology. About 20 products have been already delivered to customers engaged in development of laser equipment.

The yttrium-aluminum laser operating with a wavelength of 1.064 microns is one of the most common and powerful. It is used in surgery, during treatment of various materials, within scientific researches, at manufacture of laser rangefinders and target designators.
