Beschreibung
Zusammenfassung:	A fibre laser is disclosed comprising a single mode or low-order-mode cladding pumped fibre laser oscillator or preamplifier, a cladding pumped fibre laser power amplifier to guide multiple transverse modes, wherein an output from the oscillator or preamplifier is applied through a mode mixing means to the power amplifier. The laser power amplifier is of greater core and cladding diameter than the oscillator or preamplifier, thus enabling lower brightness pump sources to be employed.
