“…Compared to those common multi-wavelength fiber lasers limited by multiple densely spaced longitudinal modes around the central lasing wavelength, MW-SFFLs have greater potential applications, such as coherent optical orthogonal frequencydivision multiplexing and coherent dense wavelength division multiplexing (DWDM) [5], high-precision detection and high-resolution spectroscopy [1], and so on. Moreover, MW-SFFLs around 1.0 µm band increasingly arouses the researchers' interest for the huge potential in kilowatt-level narrow-linewidth fiber lasers based on master-oscillator power amplifier configuration, offering more possibilities for further development of laser weapon and gravitational-wave detection [6][7][8].…”

A continuously spacing-tunable multi-wavelength single-frequency fiber laser (MW-SFFL) at 1.06 μm is investigated based on cascaded four-wave mixing (CFWM) in a high-nonlinearity photonic crystal fiber (HN-PCF). By using two separate wavelength-tunable continuous-wave (CW) SFFLs for pumping the HN-PCF, the MW-SFFL with up to ten stable wavelengths is generated under a total pump power of 890 mW. Furthermore, when the wavelength and the power of pump lasers are appropriately manipulated, the wavelength spaces of the MW-SFFL can be tuned freely within 166 pm and the numbers of wavelengths can be controlled to 4, 6, 8, and 10, respectively. To our knowledge, it is demonstrated for the first time that the MW-SFFL based on CFWM at 1.0 μm band are directly excited by CW SFFLs.
