Multi-wavelength-tunable thulium-doped fiber laser generation based on dual-pass Mach–Zehnder and Sagnac loop hybrid filters

A wavelength-tunable thulium-doped fiber laser (TDFL) based on a Mach–Zehnder (MZ) filter and Sagnac loop was proposed in this study. The dual-pass MZ fiber filter, and Sagnac loop were fabricated to operate as reflectors in a linear cavity. The laser operating threshold was set to 138 mW. A single-...
