Fabrication and Spectroscopic Properties of Transparent Yb:YAG Laser Ceramics

Abstract:

Yb³⁺ doped YAG ceramics have been successfully fabricated using a vacuum reactive sintering method. High purity Y₂O₃, Al₂O₃ and Yb₂O₃ powders were used as the starting materials. Samples of 5.0 at.% Yb³⁺ doping concentration have been obtained. The in-line transmittance of the sample reaches 84% at 1100 nm wavelength. The absorption and emission bandwidth were measured to be 19.5 nm and 11.07 nm respectively. The results show that Yb:YAG ceramics will be a promising laser material for high power and ultrafast laser applications.
