The use of a narrow-wavelength tunable narrow-line laser as the pumping seed light source and the pseudo-random phase-modulated pump light to suppress the stimulated Brillouin (SBS) scattering effect in the highly nonlinear optical fiber, combined with a high power erbium-doped fiber amplifier Fiber Optic Parametric Oscillator High-power pumping delivers stable multi-wavelength laser output at room temperature through four-wave mixing (FWM). The wavelength interval of MW-FOPO can be tuned by adjusting the pump wavelength. In the spectral range of 1505 ~ 1615 nm, 17 multiwavelength spectra with extinction ratio greater than 10 dB were obtained. Experiments show that MW-FOPO achieves the excellent characteristics of multi-wavelength laser source.
