High power resonantly pumped holmium-doped fibre sources

摘要

Holmium-doped fibres provide a power scalable gain-medium capable of operation at wavelengths beyond 2.05 μm. We discuss and review our approach to the power scaling of pulsed and CW laser sources at 2.1 μm using holmium-doped fibres. This paper outlines experiments which demonstrate the wavelength region accessible using holmium-doped silica fibres, as well as a linearly polarised pulsed master-oscillator power amplifier and high average power CW laser and amplifier systems. These devices demonstrate the applicability of holmium fibre lasers to a range of scientific, medical, industrial and defence applications.
