Thulium Oxide (Tm2O3) Powder Application
Thulium Oxide, also called Thulia, is the important dopant for silica-based fiber amplifiers, and also has specialized uses in ceramics, glass, phosphors, lasers. Because the wavelength of Thulium-based lasers is very efficient for superficial ablation of tissue, with minimal coagulation depth in the air or in water. This makes Thulium lasers attractive for laser-based surgery. It can also be used in portable X-ray devices that have been bombarded in a nuclear reactor as a radiation source.
