Abstract :
A singly Ho3+-doped fluoride fibre laser that uses energy transfer upconversion to maintain the population inversion has produced 340 mW at 2.92 μm. The ∼1100 nm output from a diode-cladding-pumped Yb3+-doped silica fibre laser was used as the pump source and a maximum slope efficiency of 5% was obtained.
