Abstract :
Signal gain saturation and crosstalk characteristics in two-channel common amplification were investigated using a 1.5μm travelling-wave laser amplifier. Simultaneous amplification in the two channels causes gain saturation of the other, which results in an approximate 3 dB reduction in saturation output power. The total output power is confirmed to dominate the gain saturation in laser amplifiers.
