PURPOSE: To provide an optical fiber amplifier which is highly stabilized regardless of the wavelength of excitation light. CONSTITUTION: In an optical fiber amplifier which multiplexes waveforms of excited light and signal light, enters them into an optical fiber doped with rare earth elements, and amplifies signal light by stimulated emission with the excitation light in the optical fiber, a modulated signal generating circuit 2 which modulates the excitation light outputted from an excitation light generating circuit 1 is provided. |
