摘要
采用中频感应加热提拉法,生长Nd,Yb:YAG激光晶体.利用XRD、吸收光谱和荧光光谱对晶体的物相结构及光谱性能进行分析,结果表明:Nd,Yb:YAG晶体属于立方晶系,晶格参数a=1.2021 nm,在808 nm处有较强的吸收能力.室温下,Nd,Yb:YAG晶体荧光光谱的最强荧光发射峰位于1 030 nm处,归属于Yb3+离子的2F5/2—2F7/2能级跃迁.
To produce Nd, of Yb: YAG laser crystal by use of medium frequency induction heating Czochralski method. Taking advantage of the XRD, absorption spectra and fluorescence spectra on the crystal of the phase structure of and spectral to analyze the performance of structure shows that: Nd, Yb: YAG crystals belong to the cubic crystal system with the lattice parameters a = 1. 2021 nm. There is a strong absorption in the 808 nm but under the common temperature Nd, Yb: YAG crystal fluorescence spectra of the strongest fluorescence emission peak at 1030 nm, attributable to the Yb^3+ ion ^2F5/2--^2F7/2 level transition.
