Two tungsten acid kalium ytterbium which are possible to be doped, the production method and use

摘要

This invention may be doped with the rare earth element ion of one or more, monoclinic system, it possesses the crystalline structure which belongs to space group C2/c two tungsten acid kalium ytterbium monocrystals [KYb (WO₄) in regard to W₂], it is used and the pump is done with the infrared ray diode the visible spectrum, as the material for the solid state laser which possesses the radiation of especially green color and blue color.
