Wavelength-tunable very high power soliton fibre lasers are constructe
d using chirped fibre Bragg gratings. Near-bandwidth limited pulses wi
th widths of 4.0 ps and pulse energies up to 10 nJ are generated direc
tly from passively modelocked erbium fibre lasers. A stable pulse repe
tition rate of 17 MHz is obtained, giving rise to an average modelocke
d output power of 170 mW.
