Abstract

A novel single-polarisation fibre amplifier design is presented. The use of a Faraday mirror in a double-pass design yields optical gain with high efficiency, without spatial hole burning and independent of gain-fibre birefringence. An amplifier, tunable polarised laser, and a high-power polarised super-fluorescent source are demonstrated.
