Abstract Investigation of room temperature laser performance of the polycrystalline Er:Y 2 O 3 ceramic at 2.7 μm with respect to dopant concentrations was conducted. With 7 at.% Er 3+ concentration Er:Y 2 O 3 ceramic as laser gain medium, over 2.05 W of CW output power at 2.7 μm 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.
