The polished slices with various Tm3+doped concentrations were transparent as shown in Fig.1.The X-Ray Diffraction(XRD)was recorded by using a XD-98X diffractometer(XD-3,Beijing).The real Tm3+concentrations in single crystal weremeasured by an inductively coupled plasma atomic emission spectroscopy(ICP-AES PerkinElmerInc,Optima 3 000).Table 1lists the measured Tm3+concentrations and the molar fractions of Tm3+in raw material.A Cary 5 000 UV/VIS/NIR spectrophotometer was used for measurement of the absorption spectra.The emission spectra were recorded under the 790 nm LD excitation by a Triax 320 type spectrometer.The fluorescence lifetime at 1.86μm were recorded with FLSP920fluorescence spectrophotometer.All these measurements were carried out at room temperature.
