Riassunto analitico
Now single crystalline fibers became the subject of increasing interest, because of their remarkable characteristics. Due to large length-to-diameter ratio composed with perfect crystal structure and chemical homogeneity, the mechanical and physical properties approach theoretical values.<br>In this work we are interested in grown of single crystal fibers for Laser, optics, non linear optics and Scintillation applications. Beside that, we are trying during this work to develop a new material that have specific thermo-mechanical properties (in particular low loss angle) to be used as a suspension for the mirror in advanced gravitation waves detector in order to decrease the low thermal noise.<br>
