|Abstract:||We report on numerical modeling of the spectral dynamics of telecom range laser pulse of moderate power in a silica fiber with a flattened dispersion and longitudinally varying diameter. In the simulation experiments, the optimal fiber profile has been proposed for more than 60% energy transfer from the initial telecom range pulse to subpicosecond pulse at 2.2–2.3 μm. Another option of the fiber diameter profile provides flat radiation spectrum in the range 2–2.5 μm. © 2018 Elsevier Inc.|
