Abstract

Very high temperature operation of a rare earth doped fibre laser is investigated. An all-glass ytterbium-doped fibre laser is demonstrated, operating at heat sink temperatures ranging from 25°C to 400°C and output powers of > 40 W. Over this temperature range only a small reduction in laser output power was observed. The emission spectrum of this source was also measured for heat sink temperatures up to 400°C. We discuss the advantages of operating at such extended temperatures such as weight savings from reduced heat sink size, extended long wavelength operation and suppression of detrimental non-linear effects.
