(a) Center wavelengths of the most red-shifted solitons as a function of the input pulse energy into the LMA fiber. Numerical simulations: red dashed line with stars; experimental results: blue solid line with squares. (b) Measured pulse energies of the most red-shifted solitons at various soliton wavelengths. (c) Bandwidths of the most red-shifted solitons at various soliton wavelengths. Numerical simulations: red dashed line with stars; experimental results: blue solid line with squares. (d) Pulse widths of the most red-shifted solitons at various soliton wavelengths. Numerical simulations: red stars; calculated pulse widths assuming TL sech² pulse using the bandwidths in (c): blue circles; experimental results: black solid line with squares.
