Distributed feedback Er3+-doped fibre laser

Robust singlemode operation is reported of an Er/sup 3+/-doped distributed feedback fibre laser based on a 36 mm long Bragg grating with a permanently induced /spl pi//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.< >
