The phosphate glass compositions of high-average power effect is provided.It is said that this glass also demonstrates excellent chemical stability.US′
820 disclose and comprise high relative contents Al2O3And/or La2O3Particular glass.
US 4,929,387 (Hayden et al.) and US 5,032,315 (Hayden et al.) discloses and comprises on a small quantity or not
Wrap silica containing phosphate glass compositions, it is said that it is useful to high mean power laser, demonstrate high heat simultaneously
Conductance and low thermal coefficient of expansion.It is also said that the chemical stability that this glass display is excellent.Spy disclosed in US ' 387 and US ' 315
Determine glass and generally comprise alkali metal and/or the alkaline-earth metal of high relative contents, be combined with the Al of high relative contents2O3。
US 5,053,165 (Tortani et al.) discloses phosphate-based glass compositions, it is said that it is applicable to high average
Power laser is applied, and it is characterized in that strong resistance to sudden heating.The disclosed particular glass of Tortani et al. comprises relatively high
The alkali metal of content and/or alkaline-earth metal, and do not comprise SiO2Or B2O3。
US 4,820,662 (Izumitani et al.) discloses phosphate glass compositions, wherein phosphate laser glass
Key component P2O5A part by SiO2Replace, to reduce thermal coefficient of expansion and to increase shock resistance.For offset due to
Substantial amounts of SiO in phosphate2And the deterioration of the chemical stability caused, can be by Al2O3Add this glass.It is also said that use Al2O3Take
For part SiO2Stimulated emission cross section can be reduced.The disclosed particular glass of Izumitani et al. comprises the alkali gold of high relative contents
Belong to, be combined with the SiO of relatively high total content2And Al2O3。
US 6,853,659 (Hayden et al.) disclose a kind of use high doped phosphate-based glass compositions swash
