摘要： An optical amplifier includes an optical amplification medium which has simultaneous inputs of a WDM signal light and a pumping light and amplifies the WDM signal light, a pumping light source, and an amplification characteristic supervisor part which evaluates the gain tilt of amplified WDM signal lights. The supervisor part is provided in advance with a record of the relation between the medium output light power and the pumping light power corresponding to the output light power in terms of a number of proper curves plotted for certain gain tilts, and adapted to select a proper curve which is nearest to the relation in operation between the power of the pumping light which is incident to the medium in operation and the resulting amplified output light power from among the recorded proper curves, thereby determining the gain tilt of the medium based on the selected proper curve.
