We have studied the mechanism of soliton formation in a passively mode-locked fibre ring laser when the gain is increased. We show experimentally that new soliton pulses in the laser are generated by soliton shaping of dispersive waves. Our observation is further confirmed by numerical simulations where an improved model is used that takes into account explicitly the polarization dispersion effect and discrete saturable absorber effect.
