Abstract: An optical fibre laser or amplifier comprising an optical fibre and a pump radiation source configured to generate pump radiation which is received through an input end of the optical fibre. The optical fibre may include a doped core which is configured to guide the pump radiation and to generate or amplify and guide signal radiation when pump radiation passes through it. The optical fibre laser or amplifier may include a first reflector configured to reflect pump radiation and further comprises a second reflector configured to selectively reflect a portion of pump radiation. The selection of the portion of pump radiation to be reflected by the second reflector depends upon one or more of: the spatial position of the pump radiation, the direction of the pump radiation, and the polarisation of the pump radiation.
