Spatial holeburning caused by ununiform widening of erbiumdoped fiber barricades the fully gaincontrolled amplification of laser with single wavelength. A novel configuration of automatic gainclamped optical erbiumdoped fiber amplifier is presented, and a high-birefringence fiber Bragg grating is used to generate pumping lasers, peaks of which are written at 1549.3 nm and 1549.83 nm with a wavelength spacing of 0.53 nm. By adjusting a polarization controller, single or dual laser gain control is realized. The design has a gainclamped bandwidth of 40 nm (1530～1570 nm). Within the dynamic range of input power -40～-15 dBm, the average gain and noise figure of the dual laser gain controlled erbiumdoped fiber amplifier are approximately 22.22 dB and 8.69 dB, and their excursions are limited in 0.69 dB and 1.51 dB, respectively. The system performance testing shows that the more stable characteristic of dual laser controlled erbiumdoped fiber amplifier is an obvious advantage over the single laser controlling.
