Growth and characterization of KTi1 − xZrxAsO5 single crystals

Abstract Single crystals of KTi 1 − x Zr x AsO 5 of optical quality, isomorphous with KTP, were grown using the high-temperature self-flux technique. X-ray diffraction studies showed changes in the structure for 0 ≤ x ≤ 0.4 increase from orthorhombic ( x = 0) to a presumed rhombohedral structure R3m ( x ≥ 0.4). The structural transformations are accompanied by changes in the form of UV/IR fundamental absorption edges and light scattering. Second harmonic generation from 1.064 μm Nd:YAG laser radiation was obtained at 0 x μm .
