| Abstract: | High-doped Yb∶YAl3 (BO3)4 (Yb∶YAB) crystals were grown by the flux method using K2Mo3O10 as the flux. The efficient segregation coefficient was measured by using EPMA. The absorption and fluorescence spectra was measured at room temperature and compared the spectral parameters with Yb∶YAB of other Yb3 concentrations. With the increase of the Yb3 concentration, the main absorption and fluorescence peaks almost do not change, but the absorption coefficient and FWHM increase. The defects were investigated by using chemical etching method. The main defects are cracks, inclusions, dislocations and twins, which of them are more than low-doped crystals. |
