PURPOSE:A material for forming an optical waveguide of CO2 gas laser, obtained by adding specific amounts of ZnO and K2O to a GeO type glass, and having a slight transmission loss without the deliquescence. CONSTITUTION:Germanium dioxide glass consisting of 80mol% GeO2, 10mol% ZnO and 10mol% K2O is used as a glass fiber material for CO2 gas laser. The GeO2 glass of pure composition has a frequncy of minimal transmission loss in disagreement with that of the CO2 gas laser, and K2O is added to reduce the loss as a waveguide and suppress the accompanying increase in the deliquescence by the addition of ZnO. The resultant waveguide of the above-mentioned composition has improved performance as a hollow optical waveguide of the CO2 gas laser. |
