Spectral beam combining of cladding-pumped Tm-doped fibre lasers

Spectral beam combining of cladding-pumped Tm-doped fibre lasers
Tm-doped silica fibre lasers offer excellent potential for power-scaling owing to a very broad linewidth (>300nm) and relatively high lasing efficiencies.

There is limited scope for increasing the core size whilst maintaining good output beam quality and immunity from thermal effects. One attractive solution is to use multiple fibres and wavelength-combine their outputs using an intracavity diffraction grating. Here we present preliminary results for a wavelength-combined Tm-doped fibre laser with 14W output power in the 2µm spectral region.

Abstract

Tm-doped silica fibre lasers offer excellent potential for power-scaling owing to a very broad linewidth (>300nm) and relatively high lasing efficiencies. Output powers from fibre lasers are however ultimately limited by damage to the core due to its small size. There is limited scope for increasing the core size whilst maintaining good output beam quality and immunity from thermal effects. One attractive solution is to use multiple fibres and wavelength-combine their outputs using an intracavity diffraction grating. Here we present preliminary results for a wavelength-combined Tm-doped fibre laser with 14W output power in the 2µm spectral region.
