Paper Abstract

After many experimental investigations of passive harmonic mode-locking erbium doped fiber ring laser cavity, we have observed some new typical characteristics of the solitons and we propose here a circular cavity laser where a high frequency cavity transmission modulation is possible by sending a reflected pulse into the cavity, in the opposite direction to the direct pulse. The pre-saturation of the absorber and the gain depletion at the optimum frequency, superposed on the natural effect of harmonic state, determine a stable harmonic solitonic state. In this mode we can better estimate the importance of the role of unstable continuous waves and of gain recovery in forming a stable equidistant multisoliton state.
