Abstract
Robust singlemode operation is reported of an Er3+-doped distributed feedback fibre laser based on a 36 mm long Bragg grating with a permanently induced π/2 phaseshift. The laser is integrated into a master-oscillator/parametric-amplifier configuration, which yields an output power of 5.4 mW and has a linewidth of 15 kHz.Keywords
