The phase noise in a strong pumped fiber amplifier is measured using multi-dithering method. Its fluctuation property is qualitatively characterized by the power spectral density and integral spectral density, and it is concluded that the ratio of high frequency phase noise increases with the increase of pump power. The bandwidth requirement of the active phase control system is quantificationally estimated through evaluating the structure function of the measured phase noise. The experimental measurement and analysis show that the minimum bandwidths of the system are 830 Hz, 3.1 kHz and 10 kHz under the pump powers of 71 W, 181 W, and 230 W, respectively.
