An Nd3+-fibre laser pumped by a single stripe laser diode has been pas
sively modelocked using a semiconductor saturable absorber/end mirror
as the mode-locking element. A 6 cm length of heavily doped fibre was
used to minimise the effects of positive group velocity dispersion, an
d stable modelocking with pulses of 4 ps duration was obtained at the
laser wavelength of 1053 nm.
