Popis: We report on a high-power Ho:Y2O3 ceramic laser in-band pumped by a homemade Tm-doped all-fiber MOPA at 1941 nm. The Ho:Y2O3 ceramics fabricated by vacuum sintering and hot isostatic pressing present uniform ceramic grain and high optical homogeneity. The 24.6 W output power at ~2117 nm is successfully achieved by exploiting the advantages of in-band pumping technique, which to our knowledge is one order of magnitude higher than the previous results obtained from the Ho-doped sesquioxides ceramic lasers, indicating the power scalability of sesquioxides ceramic compared to other bulk materials in high-power laser.
