Luminescence Properties of Advanced Materials

Low-temperature absorption and fluorescence spectra of the Yb3+ ions were measured in phosphate glass with compositions of (60–65)P2O5–(4–8)B2O3–(5–10)Al2O3–(10–15)K2O–(5–10)BaO–(0–2)La2O3–(0–2)Nb2O5–(4–8)Yb2O3 (mol%). Temperature dependence of lifetime of Yb3+:2F5/2 level was investigated. Laser performance of sample pumped by 940 nm laser diode at low temperature were presented. At 8 K, laser oscillation of diode pumped Yb3+: phosphate glass yielded a slope efficiency of 4% and a maximum power of 2 mW, the peak laser wavelength is 1001 nm.
