Times Cited Count:16 Percentile:58.79(Materials Science, Multidisciplinary)The temperature and energy dependence of spin excitations in an optimally P-doped BaFe(AsP) superconductor (T = 30 K) were studied by using inelastic neutron scattering. Experimental results are consistent with calculations from a combined density functional theory and dynamical mean field theory, and suggest that the decreased average pnictogen height in BaFe(AsP) reduces the strength of electron correlations and increases the effective bandwidth of magnetic excitation.

Low-temperature absorption and fluorescence spectra of the Yb3+ ions were measured in phosphate glass with compositions of (60-65)PO-(4-8)BO-(5-10)AlO-(10-15)KO-(5-10)BaO-(0-2)LaO-(0-2)NbO-(4-87)YbO in mol-%. Temperature dependence of lifetime from F upper level of YB was investigated with a cryostat. The glass laser performance pumped by 940 nm laser diode was measured at different temperature range. At 8 K, glass laser oscillation had a slope efficiency of 4% and a maximum power of 2 mW at the peak laser wavelength of 1001 nm.

Times Cited Count:7 Percentile:51.64(Multidisciplinary Sciences)A new type of ytterbium doped phosphate laser glass has been produced and studied about physical and optical properties such as thermo-mechanical properties, nonlinear properties, crystalline phase, micro defects and spectroscopic properties. In the glass forming process, newly developed OH removing technology was adopted. From the reduction of OH concentration in the glass, upper state fluorescence lifetime reached 2.2 ms. Additionally, the glass shows remarkable athermal property of 0.4210E/K, which is around one-tenth of QX/Yb glass.
