摘　　要：A stable three-channel dual-wavelength fiber ring laser is proposed and experimentally demonstrated. The dig- ital mieromirror-deviee （DMD） processor can select and reeirculate any dual waveband from the gain spectrum of the erbium-doped fiber at each channel. The uniform and stable dual-wavelength oscillation is obtained by a highly nonlinear photonic crystal fiber, which causes two degenerate the four-wave-mixing processes. By loading different reproducibility diffraction gratings on the optoelectronic DMD processor, the laser can be operated stably in a three-channel dual-wavelength scheme at room temperature. The power fluctuation of each laser channel is less than -0.02 dB.A stable three-channel dual-wavelength fiber ring laser is proposed and experimentally demonstrated.
