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.
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.
