Abstract:
Yb0.140 Gd0.813La0.047VO4 crystal was grown by the Czochralski method. The effective segregation coefficients of Yb3+ and La3+ ions in crystal are 0. 80 and 0. 47, respectively. The doping ion of La3+ can improve the laser damage threshold and the stability of crystal-growth process of Yb: GdVO4 crystal, weaken the fluorescence quenching and the fluorescence trapping effects of high Yb3+-doped crystals. The crystal has large the full widths at half maximum (FWHM) of the absorption and fluorescence spectra, which is 26nm and 47nm, respectively, and the large absorption cross section and emission cross section that is 2.26 × 10-20 cm2 and 0. 96 × 10-20 cm2, respectively. So Yb0.140Gd0.813La0.047VO4 crystal may be applicable for femtosecond laser and for the tunable laser.
