和发射截面比较大.Yb:CaF2一SrF2(19%)晶体在1040nm附近的发射截面比较大,光谱也比较宽.这说明在掺杂相 同浓度Yb时,混晶中CaF2,SrF2的比例不同,晶体的光谱性质不同,主要原因是在混晶中晶体的无序度不同,晶体 对称性降低,形成低对称光学中心.从热扩散系数计算的热导率结果看出晶体具有比较好的热导率. 关键词:...

However, the decay lifetimes decreased with increasing Yb content, and 1–5% Yb: SrF2 transparent ceramics had decay lifetimes of 4.58, 3.48, 3.22, and 3.19 ms, respectively.doi:10.1016/j.optmat.2020.109869Yiwei GaoBingchu MeiWeiwei Li
We report on the first example, to the best of our knowledge, of solid-state laser cooling in ytterbium-doped CaF2 and SrF2 crystals by anti-Stokes fluorescence. The crystals were grown by the Czochralski method in a fluorine-rich atmosphere to prevent the formation of divalent ytterbium ions....
The maximum average output power of the mode-locked Yb:SrF2 laser was scaled up to 313mW for slightly longer pulses of 70 fs at 1049.4nm, corresponding to a peak power of 51.9kW and an optical efficiency of 34.7%.doi:10.1364/OE.485177Wen-Ze Xue...
SrF2: Ei(superscript 3+), Yh(superscript 3利用水热法以聚乙二醇作为分散剂合成了Er(上标 3+)和Yb(上标 3+)共掺的SrF2纳米晶.在980mn半导体激光器激发下,研究了不同Er(上标 3+)离子掺杂浓度对发光性能的影响,确定了最佳掺杂浓度比,讨论了退火温度对样品发光的影响及样品的协作敏化和声子辅助共振能量传递的...
The hydrothermally grown SrF2:Yb,Er UCNPs are formed as nano-spheres in size ~ 30 to 60 nm. It gives a high specific surface area of 47.17 to 23.58 m g. The nano-spherical SrF2:Yb,Er resulted an intense red upconversion emission at 660 nm, under the near-infrared (NIR) 980 nm ...
通过温和水热法制备了氟化锶(SrF2):Yb,Er,Mn纳米晶.采用X射线衍射,扫描电子显微镜,荧光分析对制备的纳米晶微结构,形貌,发光性能进行表征.结果表明,纳米晶微结构为面心立方晶相,形貌为类球形,随着Mn^2+离子的掺入,样品发生晶格畸变,粒径减小,发光强度减弱,Er^3+离子的红/绿发光强度比增大,发光颜色从绿光区向...
We report on laser diode (LD) pumped passively Q-switched Yb,Gd:SrF2 lasers with high single-pulse energy for the first time,to the best of our knowledge.In addition,a stable Q-switched laser based on a Cr4+:Y3Al5O12 saturable absorber was demonstrated.The maximum output power of the ...
