چکیده
We present novel carbon-nanotube-based saturable absorbers. Using the low-temperature alcohol catalytic chemical-vapor deposition method, high-quality single-walled carbon nanotubes (SWNTs) were directly synthesized on quartz substrates and fiber ends. We successfully applied the SWNTs to mode lock a fiber laser producing subpicosecond pulses at a 50-MHz repetition rate.

Towards low timing phase noise operation in fiber lasers mode locked by graphene oxide and carbon nanotubes at 1.5 µm.
We investigate the timing phase noise of fiber lasers mode locked by graphene oxide (GO) and carbon nanotubes (CNTs), respectively, integrated in a linear cavity fiber laser in the reflecting operation. Due to the shorter decay time of the GO and CNTs, weaker slow saturable absorber effects are expected and mode-locked lasers based on these two saturable absorbers exhibit low excess timing phas...
متن کاملVector solitons in harmonic mode-locked erbium-doped fiber lasers
We report experimental study of vector solitons for the fundamental and harmonic mode-locked operation in erbiumdoper fiber lasers with carbon nanotubes based saturable absorbers and anomalous dispersion cavities. We measure evolution of the output pulses polarization and demonstrate vector solitons with various polarization attractors, including locked polarization, periodic polarization switc...
متن کاملUltrafast Stretched-Pulse Fiber Laser Mode-Locked by Carbon Nanotubes
Ultrafast fiber sources having short pulses, broad bandwidth, high energy, and low amplitude fluctuations have widespread applications. Stretched-pulse fiber lasers, incorporating segments of normal and anomalous dispersion fibers, are a preferred means to generate such pulses. We realize a stretched-pulse fiber laser based on a nanotube saturable absorber, with 113 fs pulses, 33.5 nm spectral ...
متن کاملCarbon nanotubes for ultrafast fibre lasers
Carbon nanotubes (CNTs) possess both remarkable optical properties and high potential for integration in various photonic devices. We overview, here, recent progress in CNT applications in fibre optics putting particular emphasis on fibre lasers. We discuss fabrication and characterisation of different CNTs, development of CNTbased saturable absorbers (CNT-SA), their integration and operation i...
متن کاملNew Insight on a Vertically Aligned Single-Walled Carbon Nanotube Film and an Application to All-Fiber Passive Mode-Locker
A new insight is gained on the structure of the vertically aligned single-wall carbon nanotubes (VA-SWNTs) [1-3] generated by alcohol catalytic CVD (ACCVD) technique [4]. The thickness-controlled growth of VA-SWNTs by using in-situ laser absorption method is now a routine [2]. Our recent finding of the simple removal method using hot-water [5] enabled us to transfer this film to various flat su...
