Abstract：

We　report　the　generation　of　MW-class　tunable　Raman　solitons　of　3.3–3.8　µm　in　a　fluorotellurite　fiber.　The　pump　source　of　the　mid-infrared　fiber　is　a　2.15–2.3　µm　Raman　soliton　source　which　has　the　highest　peak-power　Raman　soliton　(3.8　MW)　ever　achieved　in　a　silica　fiber.　Fluorotellurite　fiber　is　characterized　by　its　short　length　and　high　nonlinearity,　preventing　the　Raman　soliton　pulse　broadening　that　occurs　with　fiber　dispersion.　The　Raman　soliton　shifted　to　3.8　µm　while　still　maintaining　an　ultra-narrow　pulse　width　of　70.4　fs　with　1.36　W　output　power　and　1.17　MW　peak　power.　To　the　best　of　our　knowledge,　this　is　the　highest　peak-power　Raman　soliton　obtained　in　a　mid-infrared　fiber.　©　2024　Optica　Publishing　Group.　All　rights,　including　for　text　and　data　mining　(TDM),　Artificial　Intelligence　(AI)　training,　and　similar　technologies,　are　reserved.
