A forward-pumping dual-stage double-pass erbium-doped fiber source at 1.55 μm is presented and experimentally demonstrated. Broadband, high-power characteristics can be obtained simultaneously while reserving the high stability of the mean wavelength by appropriately choosing the source parameters, including the length of two sections of erbium-doped fiber and the pump power of two stages. Such a fiber source is an excellent candidate for the fiber-optic gyroscope (FOG).
