摘要
Abstract
In this study,large size and high quality alexandrite(Cr3+:BeAl2O4)crystals were grown by induction heating Czochralski method combined with automatic diameter control technology.The obtained crystal diameter size reaches 70 mm,the cylinder length reaches 140 mm,and its weight exceeds 2 800 g.Irradiated with a cold light source,there are bubbles in the center area of φ10～15 mm.No scattered particles are found in theφ8mm × 130 mm crystal rod under the irradiation of a 5 mW green laser.The wavefront distortion is 0.3λ@632.8 nm measured by a Zygo laser interferometer.The Cr3+doping concentrations were measured by inductively coupled plasma atomic emission spectrometry.The axial molar concentration gradients are 0.5×10-4～1.9×10-4 cm-1.The absorption spectra of the alexandrine crystals with different Cr3+doping concentrations at room temperature were measured by Perkin Elmer Lambda-950 UV-Vis near-infrared spectrophotometer and the absorption coefficients were calculated.These results provide important basic data for the application of alexandrite crystals.关键词
