We demonstrated high power all-fiber $2\sim 3~\mu \text{m}$ supercontinuum (SC) generation from a short piece of germania-doped fiber (GDF) pumped by a thulium-doped fiber amplifier (TDFA). As 39 W 2 $\mu \text{m}$ picosecond pulse launched into GDF, a mid-infrared SC laser with maximum average power of 33.6 W and broadband spectrum of $1.8\sim 3.0~\mu \text{m}$ was achieved, which was the record SC power in $2\sim 3~\mu \text{m}$ region based on GDF to date, to the best of the authors’ knowledge. The spectral broadening mechanism of the high-power SC generation were theoretical investigated by solving the generalized nonlinear Schrödinger equation (GNLSE).
