Nonlinear polarization rotation is used to compress pulses or suppress supermode noise in mode-locked fiber lasers at different situations. In this letter, we propose a novel method to simultaneously realize the above two effects by exploiting nonlinear polarization rotation in actively mode-locked fiber ring laser at a special state. A simple model derived by theoretical analysis is given to explain this phenomenon. We have also investigated the different transmission situations of nonlinear polarization rotation in the 10-GHz actively mode-locked fiber ring laser. Experimental observations agree well with theoretical predictions.
