Abstract :
A novel erbium-doped fibre laser cavity configuration with produces single-longitudinal-mode operation with less than 10 kHz linewidth is reported. The fibre laser operates in a travelling-wave mode which prevents spatial holeburning from occurring. A principal advantage of the configuration is that it allows the precise and stable setting of the lasing wavelength.
