Abstract

Abstract. Recent progress in high-quality transparent ceramic window materials (MgAl₂O₄ spinel and β -SiC) and high-power solid-state laser materials (Yb³⁺ : Y₂O₃, Yb³⁺ : Lu₂O₃, and Ho³⁺ : Lu₂O₃ is reported. Spinel ceramic demonstrates a record low-absorption loss of 6 ppm/cm at 1.06 μm. The capability of fabricating various shapes and sizes of spinel ceramics is also demonstrated. We also report optical transparency from a β -SiC ceramic fabricated by field assisted sintering technology (FAST). We report lasing in hot-pressed Yb³⁺ : Y₂O₃ and Yb³⁺ : Lu₂O₃ ceramic made from coprecipitated powder. The highest ever reported output power and efficiency from 10% doped Yb³⁺ : Lu₂O₃ ceramic is also presented. Lasing oscillation from hot pressed composite of five-layered Yb³⁺ : Y₂O₃ ceramic is also demonstrated for the first time.
