Multilingual: ThuliumOxid, Oxyde De Thulium, Oxido Del Tulio		 Thulium Oxide, also called Thulia, is the important dopant for silica-based fibre amplifiers, and also have 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 air or in water. This makes Thulium lasers attractive for laser-based surgery. It can also be used in portable X-ray devices that has been bombarded in a nuclear reactor as a radiation source.
