摘要
首次生长了新型激光晶体掺钬硼酸钙氧钆 (Gd COB:Ho) ,测量了它的透过谱 ,分析并标定了 Gd3+离子和 Ho3+ 离子的能级跃迁对应的峰值。计算了 Ho3+ 离子在晶体中的吸收截面。由积分吸收截面的公式及 Judd- Ofelt理论计算的振子强度 PJ,J拟合出唯象强度参量 Ωt。
The transmittance spectrum of GdCOB: Ho crystal,which was grown by using Czochraliski pulling method for the first time to our knowledge,has been measured.The absorption peak of Gd 3+ and Ho 3+ ions was labled.The absorption cross-section and oscillator streng th are calculated on the basis of its spectrum.According to Judd-Ofelt theory,t he spectral strength parameters Ω 2=3.511×10 -20 cm 2,Ω 4=1.093×10 -20 cm 2,Ω 6=0.985×10 -20 cm2 of Ho 3+ have bee n fitted. -
