Bound-state solitons in a linear-cavity fiber laser mode-locked by single-walled carbon nanotubes

Abstract

The bound-state solitons generated from a nanotube-mode-locked linear-cavity fiber laser are experimentally observed and numerically simulated for the first time to author’s best knowledge. Two chirped fiber Bragg gratings are exploited as the mirrors for the proposed laser. The pulse duration of solitons is about 6.3 ps and the pulse-to-pulse separation is about 23 ps in the experimental observations. Numerical simulations confirm the experimental results and agree well with the experimental observations. Both experimental and numerical results show that the bound-state solitons are strongly stable.
