Resumen: © 2018 Novel transparent Ho-doped sesquioxide ceramics are synthesized by high-temperature vacuum sintering and hot isostatic pressing. The spectroscopic properties of 1.4 at% and 3 at% Ho:(Lu,Sc)2O3ceramics are studied within Judd-Ofelt theory, yielding the intensity parameters Ω2= 7.863, Ω4= 1.843 and Ω6= 0.531 [10−20cm2]. The radiative lifetime of the5I7state is 10.63 ms. Absorption, stimulated-emission and gain cross-sections for the5I7→5I8Ho3+transition are calculated. At > 2 µm, the maximum σSE= 3.41× 10−21cm2at 2.101 µm. Under GaSb diode-pumping at 1.929 µm, the 1.4 at% Ho:(Lu,Sc)2O3ceramic laser generated 187 mW of quasi-continuous wave (CW) output at 2.114–2.135 µm with a slope efficiency η of 7.6%. When pumped at 1.946 µm with a Tm laser, η reached 25% while the CW output power was 20.5 mW. The Ho:(Lu,Sc)2O3ceramics are promising for broadband tunable and ultrashort pulse laser operation at ~ 2.1 µm.
