“…In the past few years, several methods have been proposed to realize multi-wavelength emission from TDFLs. In 2015, a multi-wavelength TDFL employing a phase modulator and Sagnac loop was proposed by Liu et al [6]; their proposed fibre laser can produce ten lines within the 1983-1998 nm range. In 2015, a widely tuneable, dual-wavelength, thulium-doped ring-cavity fibre laser based on a one-stage Sagnac loop was demonstrated by Jia et al [7]; the power fluctuations were below 0.7 dB.…”

A multi-wavelength thulium-doped fibre laser based on a Sagnac loop and a Mach–Zehnder filter was designed and experimentally demonstrated. In this ring-cavity fibre laser, the Sagnac loop was composed of 2 m-long polarization-maintaining fibres, and the pigtail fibre core/cladding diameter of all components was 10/125 µm. A 4 m-long thin-core fibre with a 5/130 µm core/cladding diameter was spliced into the cavity to obtain the Mach–Zehnder structure. The wavelength spacings of the comb spectra of the Sagnac loop and the Mach–Zehnder filter were 3.2 nm and 20.3 nm, respectively. When the pump power was 150 mW, single-wavelength lasing occurred with 3 nm-wavelength spacing within the 1857–1897 nm range; the maximum power difference was less than 1.27 dB; the side-mode suppression ratio was greater than 32.68 dB; and the peak power fluctuations, measured over a 10 min interval, were less than 0.2 dB. A tuneable dual-wavelength lasing mode was also realized by adjusting the polarization controllers, with emission occurring simultaneously at 1874 and 1891 nm. In this case, the power fluctuations were less than 1.36 dB and 0.53 dB, respectively. A tuneable triple-wavelength lasing mode was also demonstrated, with a side-mode suppression ratio greater than 34.51 dB.

We presented a compact and enduring multiwavelength Tm‐doped fiber laser at 2 μm employing a microfiber knot resonator (MKR). The MKR, made by the flame‐brushing technique, has a fiber diameter of 10 μm and a ring diameter of 150 μm. The MKR plays a role as both the comb filter and the power equalization device, which is critical for the stable multiwavelength Tm‐doped fiber laser. By properly adjusting the pump power, three wavelength lasing channels (1956.2, 1964.4, and 1971.8 nm) were observed stable and their average power density was around −8.76 dBm with 1 W pump power. In addition, the channel spacing is 5.8 nm with the 3‐dB bandwidth of the channel smaller than 0.5 nm. The experiments demonstrated that the MKR can be utilized as a comb filter with the suitable transmission spectrum to reach a steady multiwavelength Tm‐doped fiber laser.
