| 英文摘要 | This paper reports 2.0 mu m emission properties of tm3+/ho3+ co-doped oxyfluoride tellurite glass exited by 808 nm laser diode (ld). mid-infrared transmittance property of glass was investigated by fourier transform infrared (ftir) spectrometer. the real chemical composition of investigated glass was identified by x-ray photoelectric spectroscopy (xps). thermal stability of the glass was determined by differential thermal analysis (dta) measurement. the judd-ofelt parameters, spontaneous radiative transition probabilities, branching ratios and radiative lifetime of ho3+ were calculated based on the absorption spectra by using judd-ofelt theory. results indicate that the maximum 2.0 mu m emission intensity attributed to the i-5(7)-> i-5(8) transition of ho3+ was achieved at 1.5 mol% tm2o3 and 1 mol% ho2o3 concentrations in oxyfluoride tellurite glass. oh- absorption at 3000 cm(-1) was greatly depressed by introduction of 10 mol% f-. the maximum absorption and stimulated emission cross-section of ho3+ near 2.0 pm are 7.0 x 10(-21) cm(2) at 1950 nm and 8.8 x 10(-21) cm(2) at 2048 nm, respectively. the calculated radiative lifetime of 4.4 ms for i-5(7)-> i-5(8) transition and large stimulated emission cross-section of the tm3+/ho3+ co-doped oxyfluoride tellurite glass indicate that the glass has a potential application in efficient 2.0 mu m laser.
