We employed spark plasma sintering (SPS) in the presence of sintering aids to fabricate high-quality Ho3+
transparent ceramics suitable for use as a laser gain medium, and analyzed their microstructure and optical properties. Ho3+
transparent ceramics with different contents of Yb3+
were fabricated by SPS and exhibited high..... More
