چکیده انگلیسی
30â¯at% Er3+:GSAG single crystal was successfully grown by the Czochralski method. The dislocation of (111) face is studied using the chemical etching with the phosphoric acid etchant. The luminescence properties at 2.6-3.0â¯Âµm are systematically studied by measuring the fluorescence spectra and lifetimes to the transition of 4I11/2 â 4I13/2. The long fluorescence lifetime, high fluorescence intensity, and large gain Ïem spectra indicate that the 30â¯at% Er:GSAG crystal has the great potential for the multi-wavelength laser output at 2.6-3.0â¯Âµm. Meanwhile, the absorption and fluorescence properties of 30â¯at% Er:GSAG crystal under the gamma-ray radiation with three different intensities (35, 70, and 105â¯Mrad) have been investigated, indicate that this crystal can be considered as a promising MIR laser gain medium for being used under radiant environment. In addition, the luminescence property of 30â¯at% Er:GSAG crystal in visible and 1.5-1.7â¯Âµm was also studied, which shows the possibility to generate the laser around 1.6â¯Âµm.
