摘要
本文采用液相合成方法合成了掺钬氟化钇钡(分子式:Ho3+∶BaY2F8,简称Ho∶BYF)多晶原料,使用提拉法生长了掺钬氟化钇钡(Ho∶BYF)激光晶体,晶体生长参数:拉速0.5～1 mm/h,转速10 r/min。XRD测试表明:该晶体属于单斜晶系,空间群C2/m。测试了晶体的吸收及荧光光谱,同时计算了Ho离子对889 nm泵浦光的吸收系数及吸收截面,分别为4.84 cm-1、1.26×10-21cm2。该吸收对应于Ho3+从基态5I5到激发态5I6的跃迁,可实现3.9μm激光输出。
In this paper,the liquid phase synthesis method was used for synthesis of holmium yttrium fluoride barium [molecular formula： Ho3＋∶ BaY2F8,hereinafter referred to as Ho∶ BYF] polycrystalline raw materials.The laser crystal,barium yttrium fluoride doped with Ho3＋[Ho∶ BYF] was grown by the Czochralski method with the following parameters： growth speed（0.5-1 mm/h）,rotating speed（10 r/min）.The result of XRD test shows that the crystal belongs to the monoclinic crystal system and C2/m space group.The crystal absorption and fluorescence spectra were tested,and the absorption coefficient and absorption cross section of Ho3＋ on 889 nm were also calculated as follows： respectively 4.84 cm-1 and 1.26×10-21 cm2.The absorption peaks is corresponding to the transition of Ho3＋ from the ground state 5I5 to the excited state 5I6,by which 3.9 μm laser output can be carried out.
