Abstract

In this paper, the absorption and fluorescence spectra of Tm³⁺:LiNbO₃ crystals at room temperature were reported for the first time. The energy levels and experimental absorption oscillator strengths were obtained from the absorption spectrum. According to Judd-Ofelt theory, the intensity parameters (Omega) _(lambda ) ((Omega) ₂ equals 3.30 multiplied by 10^-20 cm², (Omega) ₄ equals 1.37 multiplied by 10^-20 cm², (Omega) ₆ equals 0.84 multiplied by 10^-20 cm²) were worked out by a least-square-fitting procedure. With these values, electric dipole oscillator strength, radiative transition probability, radiative lifetime, branching ratio and integrated emission cross-section were calculated. The potential use of Tm³⁺:LiNbO₃ crystal as a laser material was also discussed.
