A thulium doped silica based glass capable of supporting lasing activity including Tm3+as a lasing species disposed in a host composition, including oxides of germanium, silicon and tantalum. The crystalline form of this mineral is quartz. Because silica is a "universal solvent," glass compositions are continuously variable; thus, their properties (such as refractive indices, densities, resistance to chemical/thermal shock, et cetera) are also continuously variable and not constrained by the stoichiometric boundaries which fix chemical compounds' properties. Composition: soda-lime-silica glass: It has a similar composition to Type II glass but contains more leachable oxides. The SiO 2 content in silicate BG compositions is in direct relation to their chemical stability. Fused silica itself is an excellent glass, but, as the melting point of sand (crystalline silica) is above 1,700 C (3,092 F) and as it is very expensive to attain such high . Therefore, different types of glass can be made. The first material is silica, or silicon dioxide, which makes up 70% of the finished product.
