摘要：

The optical properties (absorption, luminescence and lifetime) of Tm3+-doped LiNbO3 and LiNbO3(MgO) have been measured. It has been found that the D-1(2), (1)G(4), H-3(4) and F-3(4) levels decay radiatively having temperature-independent lifetimes. These results are compared with the radiative transition rates calculated by using the Judd-Ofelt theory. It has also been found that MgO-codoping affects very slightly the optical properties of Tm3+ ions, except for a general broadening of the spectra. Oscillator strengths and Judd-Ofelt parameters are not affected by MgO codoping.
