Atomic layer graphene as saturable absorber for ultrafast pulsed lasers
Qiaoliang Bao,Han Zhang,Yu Wang,Zhenhua Ni,Yongli Yan,Zexiang Shen,Kian Ping Loh,Dingyuan Tang +7 more
TL;DR: In this paper, the authors demonstrate the use of atomic layer graphene as saturable absorber in a mode-locked fiber laser for the generation of ultrashort soliton pulses (756 fs) at the telecommunication band.
Journal ArticleDOI
Uniaxial strain on graphene: Raman spectroscopy study and band-gap opening.
TL;DR: In this article, Zhao et al. used uniaxial tensile strain to tune the 2D and G bands of graphene and obtained a band gap opening of ∼300 meV under 1% tensile tensile stress.
Journal ArticleDOI
Raman spectroscopy and imaging of graphene
TL;DR: In this article, Raman spectroscopy and imaging can be used as a quick and unambiguous method to determine the number of layers of a single-layer graphite compared to graphite.
Journal ArticleDOI
Graphene Thickness Determination Using Reflection and Contrast Spectroscopy
TL;DR: Two easy-to-use methods to determine the number of graphene layers based on contrast spectra are provided: a graphic method and an analytical method, which show that the refractive index of graphene is different from that of graphite.
