We investigate dynamics of the formation of high-power ultrashort self-similar light pulses (similaritons) in a fiber laser in the regime of positive dispersion. The physical factors limiting the energy and the pulse width of such pulses are revealed. We specify regimes where a laser system based on an ytterbium-doped fiber can generate self-similar pulses with an energy of about 80 nJ compressible to a pulse width of about 150 fs through extracavity linear chirp compensation.
