A single crystal of BaCaBO3F (BCBF) has been grown by the Czochralski pulling method in air. This compound was investigated for nonlinear optical applications especially in the ultraviolet. This BCBF material has a hexagonal structure with P (6) over bar 2m space group (Z=3) [D.A. Keszler, A. Akella, K.I. Schaffers, T. Alekel, Mater. Res. Soc. Symp. Proc. 329 (1994) 15]: its cell parameters are a=9.0489(8) angstrom and c=4.3257(4) angstrom. Its basic structural unit is [BO3](3-) [D.A. Keszler, A. Akella, K.I. Schaffers, T. Alekel, Mater. Res. Soc. Symp. Proc. 329 (1994) 151 group. The UV absorption edge was measured at 210 nm. The refractive indices were measured by the minimum deviation technique and fitted to the Sellmeier equations. In this article, second harmonic generation (SHG) and third harmonic generation (THG) phase-matching angle calculations are discussed. (c) 2009 Elsevier B.V. All rights reserved.
