Abstract :
A modelocked bismuth-doped soliton fibre laser is reported. A stable passively modelocked operation in an anomalous dispersion regime is achieved using a dilute nitride (GaInNAs)-based semiconductor saturable absorber mirror and a transmission grating pair for dispersion compensation. The laser generated 0.9 ps soliton pulses with a repetition rate of 7.5 MHz and wavelength tunable from 1153 1170 nm. These are the shortest pulses obtained so far from Bi-doped fibre lasers.
