Paper Title:
Growth and Absorption Spectrum of Tm,Ho:BaY2F8 Crystal
  Abstract

The Tm,Ho:BaY2F8 single crystal was successfully grown by the Cz method. The optimal technical parameters obtained are as follows: the pulling rate is 0.5—0.6mm/h; the rotation speed is 5—7rpm; the cooling rate is 10°C/h. The result of XRD curve shows that as-grown Tm,Ho:BaY2F8 laser crystal belongs to the monoclynicsystem and space group I41/a, the cell parameters calculated are: a = 0.69829 nm, b = 1.0519 nm, c = 0.42644 nm, β=99.676°, Z=2. Absorption spectra of Tm,Ho:BaY2F8 laser crystal at room temperature were measured and analysed, the absorption cross-section at 781nm calculated are 7.66×10-21cm-2.
