Intensity parameters of Tm3+ doped Sc2O3 transparent ceramic laser material

Abstract This work is focused on spectral investigations of Tm3+ doped Sc2O3 transparent ceramic as potential material for diode-pumped solid-state laser emitting around 2 μm. In the context of the Judd–Ofelt (J–O) theory a series of spectroscopic parameters such as J–O intensity parameters, oscillator strengths, radiative transitions probabilities, and radiative lifetimes as well as branching ratios are evaluated. The gain cross-sections which lead to an estimation of the probable operating laser wavelength for the 3F4 → 3H6 Tm3+ laser transition were also calculated.
