The generation of ultrashort pulses in an all-fiber erbium ring laser with a highly nonlinear cavity is mathematically modeled. It is shown that ultrashort pulses with the characteristics of both stretched pulses and solitons are generated in a highly nonlinear fiber cavity. The evolution of the width, energy, and spectral width of the ultrashort pulses in the fiber laser is obtained in the mathematical analysis. It is shown that an ultrashort pulse in a highly nonlinear cavity has a minimum width of about 200 fs, a maximum spectral width at half-height of about 17 nm, and a maximum energy of about 180 pJ. The modeling results are verified by comparing them with experimental data.
