Mode-locked erbium fibre laser with wavelength selection by means of fibre Bragg grating reflector

Mode-locked operation of a diode-pumped erbium doped fibre laser is described in which an optically written fibre Bragg reflection grating is used to define the operating wavelength. Pulses of 35 ps duration have been generated at a repetition rate of 5 GHz with mean (peak) output powers of 5mW(29mW).
