Abstract

We report results for high quality transparent ceramic window materials (spinel and β-SiC) and high power solid state laser materials (Yb:Y₂O₃ and Yb:Lu₂O₃). Spinel ceramic demonstrates a record low absorption loss of 6 ppm/cm at 1.06 μm. We also report optical transparency from a β-SiC ceramic fabricated by the Spark Plasma Sintering technique. Capability of fabricating various shape and size of spinel ceramics is also demonstrated. We report lasing in hot pressed Yb³⁺:Y₂O₃ and Yb³⁺:Lu₂O₃ ceramic made from co-precipitated powder. Highest output power and efficiency from heavily doped Yb³⁺ doped Lu₂O₃ ceramic are reported.
