Abstract
We investigate characteristics of the modulator and classify the modulation regions to study pulse-amplitude equalization (PAE) of a rational-harmonically mode-locked fiber ring laser pulses. PAE was accomplished experimentally in a polarization-maintaining laser resonator simply by optimizing the modulator driving power without any additional devices, and stable pulse-amplitude-equalized pulses were obtained in the monotonic region of the modulator at repetition rates of 20 GH, 30 GH, and 40 GH.
