We report an all-fiber continuous wave source, tunable between 1935-1980nm, based on parametric conversion combined with thulium amplification. More than 150mW of power and 30dB optical signal-to-noise ratio is obtained over the entire range. OCIS codes: (190.4975) Parametric processes, (230.2285) Fiber devices and optical amplifiers, (060.4370) Nonlinear optics, fibers.
