Dissipative Solitons characteristics in passively mode-locked Yb-doped fiber laser under limitation of gain saturation energy

Abstract

This paper is devoted to research the characteristics of the dissipative solitons formed in a passively mode-locked Yb-doped fiber (YDF) laser under limitation of the gain saturation energy. The parabolic shape dissipative solitons with linear chirps are observed in the fiber laser. The influences of the gain saturation energy on pulse duration, peak power and single pulse energy of the dissipative solitons are investigated in-depth.
