  • Aluminophosphate glass composition
    Patent number: 9834469
    Abstract: The invention relates to phosphate-based glasses suitable for use as a solid laser medium, doped with Er3+ and sensitized with Yb, in “eye-safe” applications. In particular, the invention relates to improving the physical properties of such phosphate-based laser glass composition, particularly with regards to strength of the glass structure and improved thermal shock resistance.
    Type: Grant
