optical material application not only as laser hosts but also as phosphors and scintillators. Most of laser host materials have been obtained as single crystals by Czochralski method. However, the materials in the form of transparent ceramics have comparable or even better important properties than

n turn only approximately describe real physical systems. For example, the harmonic oscillator describes a vibrating diatomic molecule only when the vibrations are not too violent and anharmonic forces are negligible. In a similar vein, it is possible to find the energy levels of the hydrogen atom u
