Abstract

The selection of the flux and the design of the proper processes are the key factor for the growth of Yb:KGd(WO₄)₂ laser crystal. Yb:KGd(WO₄)₂ crystal was grown by the Top Seeded Solvent Growth (TSSG) method using K₂W₂O₇ as a suitable flux. On the base of TG-DTA, the crystal has two obvious absorption peaks at 1086°C and 1021°C, its melting point is 1086°C, phase transition temperature from tetragonal to monoclinic is 1021°C. The Yb:KGd(WO₄)₂ crystal consists of WO₆ octahedra which consists of WOOW double oxygen bridges and WOW single bridges. IR and Raman spectra show the atom group WO₄^2- flex vibration at 436 cm^-1 and atom group WO₄^2- bend vibration at 740-925 cm^-1, WOOW double oxygen bridge vibration at 903, 765, 684, 438, 498 and 297cm^-1, WOW single bridges vibration at 808, 526 and 232 cm^-1. Analyzing on the X-ray diffraction spectrum of Yb:KGd(WO₄)₂ crystal powder sample, we can conclude that the β-Yb:KGd(WO₄)₂ crystal is of a monoclinic system, and C2/c space group.
