Growth of Oxide Laser Crystals by Czochralski Method

The growth of series of actual laser crystals belonging to di erent structural types by the Czochralski method is presented. The primary attention is given to single crystalline compounds and their solid solutions with garnet structure (scandium-containing rare-earth garnets with general formula {LnSc}3[ScMe]2Me3O12, Me = Al, Ga) as well as with olivine (forsterite Mg2SiO4) and scheelite struct...

Czochralski Growth of Oxide Crystals: Numerical Simulation and Experiments

A mathematical model that explores the basic transport phenomena in a Czochralski process, their interaction and influence on the growth of high quality oxide crystals is presented. Rare earth garnets YAG and Nd-doped YAG are considered as representative oxide materials for the purpose of modeling and numerical simulation. The model proposed is evolutionary in time, and axisymmetric in space. A...

Orthoferrite Single Crystals Growing by Modified Czochralski Method and their Properties

To obtain bulk? large-sized orthoferrite single crystals with different rare-earth elements a new crystal growth technology is proposed including modified Czochralski method and using no metal crucibles for melt suspension. For this purpose two unusual Czochralski method modifications are used. In the first one the melt of crystall~zed material 1s obtained at heating the upper surface of pol~cq...

Development of Crystal Growth Technique of Silicon by the Czochralski Method

We report on the Czochralski method for single silicon crystal growth and discuss heat and mass transfer and defect formation in the crystal. A re ector was used for separation of the heating and cooling areas in the furnace enabling us to speed up crystal growth. The melt ow to stabilize the temperature distribution in a crucible was controlled using transverse magnetic elds in a large-scale s...

Pr9.33(SiO4)6O2 Crystals: Czochralski Growth and Near UV-Visible FR Performance

Pr9.33(SiO4)6O2 crystals have been grown by the Cz-method for the first time for near UV–visible Faraday rotation applications. Rietveld refinement of XRD data demonstrates that the compound crystallizes in the oxyapatite structure with space group P63/m, with oxyapatite structure. In contrast to Tb3Ga5O12, Pr9.33(SiO4)6O2 crystal shows a higher transparency in the UV–visible wavelength region,...
