Yb:YAG晶体
Yb:YAG晶体,掺镱钇铝石榴石晶体由孚光精仪进口,孚光精仪是中国进口激光器件的第一品牌, 最大的进口精密光学器件和仪器供应商!精通光学,服务科学.提供的Yb:YAG晶体,掺镱钇铝石榴石系高质量原装进口晶体, 在国外生长, 切割,抛光,高质量的镀膜,并进行严格的质量控制后进口到国内,质量非常优异,在中科院上海光机所,安徽光机所,中国工程物理研究院等单位成功使用。 Y Yb:YAG晶体,中文名掺镱钇铝石榴石,是应用前景广阔的激光工作物质。Yb:YAG晶体或掺镱钇铝石榴石晶体更 适合激光二极管泵浦系统,并不适合传统的掺钕激光系统的泵浦结构。Yb:YAG晶体(Yb:YAG)或掺镱钇铝石榴石可输出0.94 μm激光,与传统的Nd:YAG晶体相比,Yb:YAG晶体或掺镱钇铝石榴石具有更大的吸收带宽,更长的上能级寿命,3-4倍更低的单位泵浦功率热负荷。Yb:YAG晶体或掺镱钇铝石榴石在高功率半导体泵浦激光器领域,被人们认为是取代Nd:YAG 晶体的最佳选择。更多Yb:YAG晶体资料请浏览:领先的进口精密激光光学器件旗舰型服务商--孚光精仪!The Yb3+ ion exhibits a small quantum defect and a quasi-three level system with a long upper laser level lifetime (around 1 ms for Yb:YAG), which is important for energy accumulation in Q-switched lasers. The wide luminescence band of Yb3+ is advantageous for the generation of sub-picosecond pulses. Yb3+ doped crystals do not suffer from luminescence concentration quenching. Their long energy storage lifetime, broad absorption band at 940 nm and very low quantum defect make Yb:YAG and Yb:LuAG crystals superior candidates for diode-pumped high-energy lasers.Physical properties Yb:YAG Yb:LuAG Pump wavelength941 nm938 nmAbsorption cross section 8,2 . 10-21 cm27,2 . 10-21 cm2Emission wavelength1030 nm1031 nmEmission cross section2,1 . 10-20 cm22,6 . 10-20 cm2 Laser transition2F5/2 -- 2F7/22F5/2 -- 2F7/2Refractive transition1,821,84Crystal structurecubiccubicShapeRoundRectangularDimensionsmmLength, thicknessmmYb-concentrationCoatings on S1:nmCoatings on S2:nmEnd surfacesRigth angle cutBrewster cutComments
