The application provides a gain compensation method, device, optical amplifier and storage medium, and belongs to the technical field of optical communication. The method is applied to an optical amplifier. In the method, after the power of input signal light changes, the power of pump light of the optical amplifier is adjusted based on power change information of the input signal light, the input signal light is amplified by using the pump light with the adjusted power, and the input signal light is gain compensated. In this way, the input signal light can be gain compensated only by detecting the power change information of the input signal light, the optical amplifier does not need to be in a full wave state for a long time, and therefore, the failure rate of the optical amplifier can be reduced.
