METHOD FOR FORMING BULK CRYSTALS, IN PARTICULAR MONOCRISTALS OF FLUORIDES DOPPED WITH RARE-EARTH IONS
A method and a system for forming a bulk crystal starting from precursors in the molten state for solidification and growth around a seed of material having a predetermined crystalline structure is described. The crystalline solid phase obtained at the end of the growth is subjected to a first controlled cooling step performed at a first higher cooling rate until a predetermined threshold temperature is reached, and to a subsequent controlled cooling step from the threshold temperature, performed at a second cooling rate lower than the first cooling rate.
