Abstract

A high-power 83 W cladding-pumped Tm 3 + - Ho 3 + -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 12 W was exceeded. The laser operated at wavelengths near 2105 nm with moderate beam quality, i.e., M 2 1.5 . Further power scaling of the fiber laser was limited by thermal failure of the fiber ends.
