Analysis on the optical properties for the ytterbium doped silica glasses prepared by laser sintering technology

摘要

The paper demonstrates the optical properties of the ytterbium doped silica glasses that were fabricated by laser sintering technology combined with liquid phase doping method, and analyzed the influence of the fabricated process on the formation of Yb~(2+). The spectral parameters and laser performance parameters were also calculated and analyzed. The results indicate that the formation of Yb~(2+) can be effectively restrained through the optimized preparation process. The prepared ytterbium doped silica glass presents typical absorption and emission cross sections of Yb~(1+), and possesses attractive laser performance parameters. The material would have potential applications for the gain medium of large mode area photonic crystal fiber lasers.
