英文摘要 | Ho(3+) doped germanate glass sensitized by yb(3+) has been investigated for potential application as a near-infrared laser material. the characteristic temperatures are determined by differential scanning calorimeter, and the absorption and emission spectra are measured. according to absorption spectra, judd-ofelt parameters and radiative transition probabilities are calculated and analyzed by judd-ofelt theory. the intensity of emission spectra shows a strong dependence upon the yb(3+) concentration. the result also indicates that yb(3+) plays an important role in the emission of 2.0 mu m by transferring the 980 nm excitation energy to ho(3+). the energy transfer process from yb(3+) to ho(3+) is analyzed and the result shows that coefficient of the forward energy transfer yb(3+) -> ho(3+) is 19 times of magnitude larger than that of the backward energy transfer yb(3+) <- ho(3+). it is found that the highest gain in 2.0 mu m region could be achieved from the germanate glass with 5.0 mol % yb(2)o(3) and 1.0 mol % ho(2)o(3). the present yb(3+)/ho(3+) codoped germanate glass with high emission cross section of ho(3+):(5)i(7) -> (5)i(8) at 2.0 mu m and efficient energy transfer from yb(3+) to ho(3+) will be a suitable material for developing solid state lasers around 2.0 mu m.
