Abstract:
Yttrium aluminium berate YAl3(BO3)(4)(YAB) single crystals have excellent non-linear optical properties, and doped YAB crystals have important applications in laser engineering. Neutron- and X-ray powder diffraction measurements were performed on pure YAB and doped YAl1.5Ga1.5(BO3)(4) (YAB:Ga1.5) specimens to analyse the crystallographic parameters. The Rietveld refinement showed that no lattice distortion is caused by Ga doping, while the lattice parameters increased by about 1% on Ga doping. (C) 2000 Elsevier Science B.V. AII rights reserved.
