摘要：
A phase-locked fibre bundle laser oscillator made up of one or more active fibre loops as illustrated. The single mode fibre has a doped core (2) surrounded by cladding (3) and has its ends positioned in a common plane forming a two core aperture (4) which is optically polished to a twentieth wavelength. Fibre end faces (4) are coupled by index matching material (5) to a single, partially transmitting, dielectric mirror (6) and the oscillator is side pumped (10) via the output of an array of laser diodes. Also disclosed is method of forming the fibre bundle laser by winding an optical fibre onto a rotating drum to produce coherently packed layers which are then cut parallel to the drum axis to produce a looped fibre bundle.
