    Silica-based thulium-doped fiber devices operating around 810 nm would extend the spectral range covered by high-power fiber devices. The 3H4 lifetime of 58 us was measured in our highly alumina-codoped fibers that represents a significant improvement compared to pure or weakly modified silica glass (14 µs). Using a comprehensive numerical model of the fiber we have optimized the fiber laser at 810 nm. We discuss possibility of applications of the host material in amplifiers and broadband sources.
