Abstract :
Summary form only. Double-clad fibre lasers offer a means for scaling to high power with the advantage that thermal loading is distributed over a long length of fibre minimising the risk of damage. The beam quality is determined by the waveguiding properties of the core, which can easily be tailored to produce a single-mode output. The fibre used in our experiments was fabricated in-house and had a Tm-doped aluminosilicate core.
