摘要: Abstract New Yb-doped oxides have been grown by the Czochralski method. They include borates such as Ca 3 Y 2 (BO ) 4 (CYB), Gd (CaGB), Sr Y(BO (SrYBO) and Ba Lu(BO (BLuB) well silicates SiO 5 (YSO), Al 7 (CAS) SrY (SiO O (SYS). Successful growth is reported for first time in case of SrYBO. Scattering center free CAS single crystals were obtained well. Spectroscopic evaluation reveals that all those materials should be suitable diode pumping at 980 nm due to broad absorption lines, operate a quasi-3-level scheme with large crystal-field splitting Yb ground state manifold.
