Abstract: Tm3+-doped sesquioxide crystals represent promising gain media for 2.3 µm lasers owing to their low phonon energy and high thermal conductivity. However, the difficulty in obtaining high-quality crystals and the underdeveloped analysis of energy-transfer upconversion (ETU)… read more here.
