Abstract

We grew several thulium- (Tm-) doped La₂Be₂O₅ crystals and determined the concentration of the incorporated Tm using proton-induced x-ray emission. Polarized absoprtion and emission spectra of Tm:La₂Be₂O₅ were investigated, allowing the stimulated-emission cross section to be estimated with the reciprocity method and the Fuchtbauer-Ladenburg equation. We report lifetime measurements of each of the transitions from the ³F₄ to ³H₆ multiplet and relate them to the radiative lifetime. In view of these results we revisit the question of Tm:La₂Be₂O₅ as a prospective laser material for laser emission at 1.8 μm in the presense of losses and determine the pumping threshold and slope efficiency for a typical resonator geometry.
