  • Abstract
    An ytterbium-sensitised thulium-doped silica fibre laser that generates up to 75 W of output power in the 2 /spl mu/m wavelength range when cladding-pumped by a 975 nm diode stack is reported. The slope efficiency is 32% with respect to the launched pump power and the beam quality factor (M/sup 2/) is 1.3.
