Investigation of room temperature laser performance of the polycrystalline Er:Y2O3 ceramic at 2.7 mu m with respect to dopant concentrations was conducted. With 7 at.% Er3+ concentration Er:Y2O3 ceramic as laser gain medium, over 2.05 W of ON output power at 2.7 gm was generated with a slope efficiency of 11.1% with respect to the absorbed LD pump power. The prospects for improvement in lasing efficiency and output power are considered. (C) 2016 Elsevier B.V. All rights reserved.
