英文摘要Er- (3+)-doped YSGG crystals with nine different concentrations were grown successfully by Czochralski (Cz) method. The absorption, emission spectra, and the fluorescence decay curves are investigated comparably. Based on Judd-Ofelt (J-O) theory, the J-O intensity parameters Omega(t) (t = 2, 4, 6), the experimental and theoretical oscillator strengths are calculated with the absorption spectra. The results show that the 1 at. % lowly Er3+-doped YSGG crystal is more properly used in up-conversion laser applications and 5 at. % Er:YSGG crystal is a better candidate for 1.5 mu m lasers within these nine crystals, while the heavily Er3+-doped YSGG crystal is beneficial for the 2.7 mu m laser output. But if the doping concentration goes too high, the up-conversion rate of the I-4(11/2) level could be higher than that of the I-4(13/2) level, which would lead to increasing the up-conversion emission and quenching the mid-infrared emission. The 2.79 mu m laser performance of LD end-pumped 40 at. % Er:YSGG crystal is also demonstrated.
