ELECTRO-OPTICAL LASER GLASS AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2014 - IPC C03C3/16 

FIELD: chemistry.

SUBSTANCE: electro-optical phosphate laser glass includes Na₂O, CaO, P₂O₅, La₂O₃ Nd₂O₃, Sb₂O₃ with the following ratio of components, mol. %: 0.5-10 Na₂O; 0.5-5 CaO; 10-30 Sb₂O₃; 70-61.5 P₂O₅; 0.1-7.4 La₂O₃; 7.4-0.1 Nd₂O₃, wherein the sum of concentrations of lanthanum and neodymium oxides is 7.5. In order to provide improved generation parameters, hydroxyl groups are removed from the glass by bubbling molten glass mass with dry oxygen. After clarifying the glass mass, the molten glass is poured into a heated graphite mould. The glass ingot is placed in a muffle furnace where rough annealing is carried out at 380-400°C for two hours, followed by inertial cooling to room temperature.

EFFECT: invention enables to produce glass which combines laser and electro-optical properties.
