Abstract

The periodic soliton intensity variation in a passively mode-locked fiber soliton laser was investigated using the nonlinear polarization rotation (NPR) technique. A periodiclike pulse peak power variation was obtained from the simulations. It was observed that the periodic intensity fluctuation was eliminated by reducing the pump power appropriately. The experimental results show that the nonuniformity of the output pulses is an intrinsic feature of the laser and is independent of the orientation of the polarizer in the cavity but is strongly related to the pump strength.
