摘要: 单晶光纤兼具晶体材料的优异光学性能与光纤结构的紧凑性优势,是高功率、超快激光领域的研究热点。本文采用激光加热基座法成功生长了不同掺杂浓度的Nd∶LuScO3单晶光纤,通过X射线衍射(XRD)研究了单晶光纤结构,并系统研究了光谱性能,包括吸收/发射截面、荧光寿命和Judd-Ofelt(J-O)理论分析。同时还研究了掺杂浓度对荧光寿命的影响。XRD证实生长所得的Nd∶LuScO3单晶光纤为立方晶系,无杂相。通过吸收光谱计算得到Nd∶LuScO3单晶光纤在807 nm处的吸收截面为1.16×10-20 cm2,半峰全宽为10.63 nm。J-O强度参数分别为Ω2=0.67×10-20 cm2Ω4=2.59×10-20 cm2Ω6=0.85×10-20 cm24F3/24I9/24I11/24I13/2跃迁发射截面分别为0.99×10-20、2.06×10-20、0.41×10-20 cm2。研究结果表明,Nd∶LuScO3单晶光纤是一种有潜力实现近红外波段超快激光输出的增益介质。

Abstract: Crystal fibers combine the excellent optical properties of crystalline materials with the compactness advantage of fiber structure, making them a research hotspot in high-power and ultrafast laser fields. In this work, Nd∶LuScO3 crystal fibers with different doping concentrations were successfully grown by the laser-heated pedestal growth method. The crystal structure was characterized by X-ray diffraction (XRD), and the spectroscopic properties, including absorption/emission cross sections, fluorescence lifetimes, and Judd-Ofelt (J-O) analysis were systematically investigated. The effect of doping concentration on fluorescence lifetime was also examined. XRD confirms that the as-grown Nd∶LuScO3 crystal fibers possess a cubic crystal system without any impurity phases. From the absorption spectrum, the absorption cross section at 807 nm is calculated to be 1.16×10-20 cm2, with a full width at half-maximum of 10.63 nm. The J-O intensity parameters are Ω2=0.67×10-20 cm2, Ω4=2.59×10-20 cm2, and Ω6=0.85×10-20 cm2. The emission cross sections for the 4F3/24I9/24I11/24I13/2 transitions are 0.99×10-20, 2.06×10-20, and 0.41×10-20 cm2, respectively. These results indicate that Nd∶LuScO3 crystal fiber is a promising gain medium for achieving ultrafast laser output in the near-infrared wavelength range.
