TLDR
This is the shortest reported pulse duration achieved from a Tm-doped laser mode-locked by graphene saturable absorber and such cost-effective and stable fiber lasers might be considered as sources for mid-infrared spectroscopy and remote sensing.Abstract:
We report an all-fiber Tm-doped fiber laser mode-locked by graphene saturable absorber. The laser emits 1.2 ps pulses at 1884 nm center wavelength with 4 nm of bandwidth and 20.5 MHz mode spacing. The graphene layers were grown on copper foils by chemical vapor deposition (CVD) and transferred onto the fiber connector end. Up to date this is the shortest reported pulse duration achieved from a Tm-doped laser mode-locked by graphene saturable absorber. Such cost-effective and stable fiber lasers might be considered as sources for mid-infrared spectroscopy and remote sensing.read more

Vector Dissipative Solitons in Graphene Mode Locked Fiber Lasers
TL;DR: In this article, the vector soliton operation of erbium-doped fiber laser mode locked with atomic layer graphene was experimentally investigated, and it unambiguously confirms the polarization insensitive saturable absorption of the atomic layer of graphene when the light is incident perpendicular to its 2-dimentional (2D) atomic layer.
