We demonstrate an all-fiber integrated dual-wavelength Tm-doped fiber laser with an output power of 36 W by using the spectral beam combining method. The constituent lasers are operating at the wavelengths 1949 and 1996 nm and an in-house-made WDM is used for combination of these two different wavelengths. All-fiber truly single mode power combining is demonstrated for the first time in this wavelength region.EnglishFiber lasersFibersDual wavelengthLaser output powerPower combiningSingle-mode beamsSpectral beam combiningTm-doped fiber laserTwo different wavelengthsWavelength regionsSolid state lasersConference Paper10.1364/ASSL.2015.AW4A.4
