Phosphate glass samples with various Cr2C3, Yb2O3, and Er2O3 contents based upon 67P2O5·14Al2O 3·14Li2O·1K2O·4(Yb 2O3 + Er2O3) were prepared. The effect of changing concentrations of Er3+ ions (0.1-1.5 × 1019 ions cm-3) and sensitizers Cr3+ ion and Yb3+ ion (2-16 × 1018 ions cm-3 and 1.35-2.3 × 1021 ions cm-3 respectively) on laser performance were investigated. The thermal shock resistance of this glass was doubled after an ion-exchange chemical strengthening process in a KNO3/NaNO3 molten salt bath. Lasers with repetition rates of 20 Hz at free-running and 15 Hz at Q-switched single mode were demonstrated by utilizing chemically strengthened laser glass rods.
