The variation in the modulation parameters of an optical signal in a diode power amplifier has been studied experimentally. The experimental data obtained agree well with theory that takes into account nonlinear interaction between fields in the gain medium of a laser through inversion beating. It is shown that the dominant type of output signal modulation is phase modulation, whose depth depends on the amplitude – phase coupling coefficient of the gain medium of the amplifier and the nature of the modulation (the phase relationships between the spectral components) of the output signal.
