Abstract

We developed a high-power thulium-doped fiber laser at 1907 nm with a dual-path configuration. The laser comprises a low-power seed oscillator and dual-path master oscillator power amplifiers (MOPAs). The laser has a central wavelength of 1907.4 nm and a 3 dB linewidth of 0.16 nm, with a maximum output power. Under full power conditions, the laser achieved an average output power of 154 W and 152 W. The dual-path amplifiers have a slope efficiency of 56% and 55.2%. The beam quality M² factor is about 1.5, which is recorded at the maximum operating power.
