Abstract
A high-power 83W cladding-pumped Tm3+-Ho3+-doped silica fiber laser is reported. Using bidirectional 793 nm diode pumping, a maximum slope efficiency of 42% was produced after a threshold launched pump power of 12W was exceeded. The laser operated at wavelengths near 2105 nm with moderate beam quality, i.e., M2~1.5. Further power scaling of the fiber laser was limited by thermal failure of the fiber ends.
