Thermal-Mechanical and Physical-Chemical Properties of Phosphate Laser Glasses
A compositional study of the effects of various network formers on the physical properties of phosphate laser glasses used in fusion research lasers is reported. The network formers include P<sub>2</sub>O<sub>5</sub>, AI<sub>2</sub>O<sub>3</sub>, SiO<sub>2</sub> and B<sub>2</sub>O<sub>3</sub> and most glass compositions are metaphosphates or near ultraphosphates. We have chosen Schott's commercial LG-750 laser glass as a reference composition. The results show that laser glasses having improved physical properties compared to LG-750 can be prepared by decreasing the AI<sub>2</sub>O<sub>3</sub> and increasing the P<sub>2</sub>O<sub>5</sub> content. Figures-of-merit are used to characterize the relative improvements of the various glasses studied.
