Journal ArticleDOI
A stable, wideband tunable, near transform-limited, graphene-mode-locked, ultrafast laser
Zhipei Sun,Daniel Popa,Tawfique Hasan,Felice Torrisi,Fengqiu Wang,Edmund J. R. Kelleher,John C. Travers,Valeria Nicolosi,Andrea C. Ferrari +8 more
TL;DR: In this paper, an ultrafast laser mode-locked with a graphene saturable absorber is presented. But the authors do not specify a mode-locking scheme for the sensor.
Journal ArticleDOI

Guohua Hu,Tom Albrow-Owen,Xinxin Jin,Ayaz Ali,Yuwei Hu,Richard C. T. Howe,Khurram Shehzad,Zongyin Yang,Xuekun Zhu,Robert I. Woodward,Tien-Chun Wu,Henri Jussila,Jiang-Bin Wu,Peng Peng,Ping-Heng Tan,Zhipei Sun,Edmund J. R. Kelleher,Meng Zhang,Yang Xu,Tawfique Hasan +19 more
TL;DR: A stable black phosphorus ink suitable for printed ultrafast lasers and photodetectors is demonstrated, enabling scalable development of optoelectronic and photonic devices.
Journal ArticleDOI
Tm-doped fiber laser mode-locked by graphene-polymer composite
Meng Zhang,Edmund J. R. Kelleher,Felice Torrisi,Zhipei Sun,Tawfique Hasan,Daniel Popa,Fengqiu Wang,Andrea C. Ferrari,Sergei Popov,James Taylor +9 more
TL;DR: In this article, the authors demonstrate mode-locking of a thulium-doped fiber laser operating at 1.94 μm, using a graphene-polymer based saturable absorber.
Journal ArticleDOI
Solution processed MoS2-PVA composite for sub-bandgap mode-locking of a wideband tunable ultrafast er:fiber laser
Meng Zhang,Richard C. T. Howe,Robert I. Woodward,Edmund J. R. Kelleher,Felice Torrisi,Guohua Hu,Sergei Popov,J. Roy Taylor,Tawfique Hasan +8 more
TL;DR: In this paper, a few-layer molybdenum disulfide (MoS2)-polymer composite by liquid phase exfoliation of chemically pristine MoS2 crystals is used to demonstrate a wideband tunable, ultrafast mode-locked fiber laser.
Journal ArticleDOI
Tm-doped fiber laser mode-locked by graphene-polymer composite
Meng Zhang,Edmund J. R. Kelleher,Felice Torrisi,Zhipei Sun,Tawfique Hasan,Daniel Popa,Fengqiu Wang,Andrea C. Ferrari,Sergei Popov,James Taylor +9 more
TL;DR: This work demonstrates mode-locking of a thulium-doped fiber laser operating at 1.94 μm, using a graphene-polymer based saturable absorber, which is a simple, low-cost, stable and convenient laser oscillator for applications where eye-safe and low-photon-energy light sources are required.
