摘要

Single crystal of Yb:LuAl_3(BO_3)_4(Yb:LuAB) was grown by the flux method for the first time. The cell parameters of the grown crystal were estimated by X-ray diffraction analysis. The result indicates the symmetry of trigonal space group R32, with lattice parameters a = b = 9.26372 A, c = 7.21405 A, V = 536.14 A~3, and Z = 4. The absorption and emission spectra of Yb:LuAB crystal at room temperature has also been studied. The fluorescence lifetime for Yb:LuAB crystal is about 1.48 ms. The heat capacity was measured from 25 to 500 ℃. Its second harmonic generation efficiency in LuAl_3(BO_3)_4 crystal is 3-4 times that of KDP crystal. These results show that Yb:LuAB crystal would be a potential self-frequency-doubling laser crystal.
