We report bound states of solitons from a harmonic mode-locked fiber laser based on a
solution-processed graphene saturable absorber. Stable soliton pairs, 26.2 ps apart, are
generated with 720 fs duration. By simply increasing the pump power, the laser can also
generate harmonic mode-locking with harmonics up to the 26th order (409.6 MHz repetition
rate). This is a simple, low-cost, all-fiber, versatile multifunction ultrafast laser that could be
used for many applications.
