Optical absorption and luminescence of Tm3+-doped LiNbO3 and LiNbO3 (MgO) crystals

Optical absorption and luminescence of Tm3+-doped LiNbO3 and LiNbO3 (MgO) crystals
Optical absorption and luminescence of Tm3+-doped LiNbO3 and LiNbO3 (MgO) crystals
The optical properties (absorption, luminescence and lifetime) of Tm3+-doped LiNbO3 and LiNbO3(MgO) have been measured. It has been found that the 1D2, 1G4, 3H4 and 3F4 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 strenghts and Judd-Ofelt parameters are not affected by MgO codoping.

Abstract

The optical properties (absorption, luminescence and lifetime) of Tm3+-doped LiNbO3 and LiNbO3(MgO) have been measured. It has been found that the 1D2, 1G4, 3H4 and 3F4 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 strenghts and Judd-Ofelt parameters are not affected by MgO codoping.
