[Active Glasses] Phosphate based laser glass for high power and ultra-short pulse applications [1] 
APG-1 is a phosphate glass with enhanced thermal mechanical properties desirable in high-average power applications. The broad emission bandwidth of these materials has been utilized in femtosecond regime laser systems. The lower gain cross-section and the long low concentration emission lifetime have made this glass of interest in applications limited by amplified stimulated emission and/or intended for excitation by diode lasers.
