We demonstrate, for the first time, to best of our knowledge, an all-fiber figure-of-9 double-clad Tm-doped fiber laser operating in dissipative soliton resonance (DSR) regime. Stable mode-locked rectangular pulses are obtained by using nonlinear amplifying loop mirror (NALM) technique. A long spool high-nonlinearity (HNLF) and a segment SMF-28 used enhance nonlinearity NALM obtain large all-anomalous Output power pulse energy further boosted three-stage master oscillator amplifier (MOPA) system. At maximum pump power, average output up 104.3 W with record 0.33 mJ is achieved 2 μm DSR-based MOPA
