Hysteretic behavior for transmission curve and soliton temporal separation in multi-pulsing regime for mode-locked fiber lasers

Abstract

In this work we present an experimental study of the hysteretic behavior of an Yb mode-locked fiber laser in a multi-pulsing regime. Our main focus is on the internal nonlinear transmission curve of the laser, which is fundamental to obtain the mode-locking regime. We have also observed hysteresis in the the temporal separation between dispersive bound solitons. These results have been interpreted in terms of the negative and positive feedback and the redistribution of the solitons energy.
