Experimental results indicate that K2Mo3O10 is the most favorable flux for the growth of Yb:YAB. Based on the measured refractive indices, type I phase matching angle is calculated as theta (m) ( I ) = 34 degrees 12', which agrees well with the experimental result, theta (m) ( I ) = 34 degrees 38'. In the absorption spectra of this crystal, there exist two absorption bands located at 956 and 975 nm, respectively, which are suitable for InGaAs diode laser pumping, pi polarized absorption is slightly stronger than sigma polarized absorption at room temperature. In the fluorescence spectra, there are two fluorescence peaks located at 1.03 and 1.04 mu m respectively. The fluorescence lifetime at 1.03 mu m is 1.379 ms. The estimated emission cross section is in the magnitude of 10(-21) cm(2).展开更多
