We describe a new Er3+-doped fibre laser configuration which produces single-longitudinal operation in the 1.5µm region with less than 10kHz linewidth. The fibre laser operates in a travelling-wave mode, preventing spatial holeburning. An added advantage of the configuration is that it allows precise and stable setting of the laser wavelength.
