Femtosecond　pulses　in　the　2-2.4　mu　m　spectral　region　have　potential　applications　in　many　fields,　such　as　two-photon　fluorescence　imaging,　sensitive　molecular　spectroscopy,　and　nonlinear　laser　system.　As　the　energy　is　proportional　to　the　square　of　the　soliton　order,　the　high-energy　soliton　pulse　can　be　achieved　by　promoting　the　soliton　order　during　the　soliton　splitting　and　soliton　self-frequency　shifting　processes.　We　demonstrated　high-energy　Raman　solitons　with　wavelengths　tunable　from　1.96　to　2.39　mu　m　in　a　thulium-doped　silica　fiber　amplifier.　The　maximum　pulse　energy　of　the　soliton　was　about　65.1-nJ　with　the　corresponding　wavelength　of　2.39　mu　m,　which,　to　our　knowledge,　was　the　farthest　and　the　highest　energy　soliton　pulse　generated　in　commercial　single-mode　silica　fiber.
