TL;DR: In this article, a ring-cavity thulium fiber laser with a single-wall carbon nanotube absorber was used in transmission, achieving an average output power of 3.4 mW.
Abstract: We report a ring-cavity thulium fiber laser mode locked with a single-wall carbon nanotube absorber used in transmission. A carboxymethyl cellulose polymer film with incorporated carbon nanotubes synthesized by the arc discharge method has an absorption coinciding with in the amplification bandwidth of a Tm-doped fiber. This laser is pumped by an erbium fiber laser at 1.57 μm wavelength and produces a 37 MHz train of mode-locked 1.32 ps pulses at 1.93 μm wavelength with an average output power of 3.4 mW.

TL;DR: In this article, a mode-locked soliton erbium-doped fiber laser was demonstrated with a saturable absorber made of a high-optical quality film based on cellulose derivative with dispersed carbon single-wall nanotubes.
Abstract: A mode-locked soliton erbium-doped fiber laser generating 177fs pulses is demonstrated. The laser pumped by a 85mW, 980nm laser diode emits 7mW at 1.56μm at a pulse repetition rate of 50MHz. Passive mode locking is achieved with a saturable absorber made of a high-optical quality film based on cellulose derivative with dispersed carbon single-wall nanotubes. The film is prepared with the original technique by using carbon nanotubes synthesized by the arc-discharge method.

TL;DR: In this article, thin polymer films (based on polyvinyl alcohol or carboxymetylcellulose) containing single-wall carbon nanotubes synthesized by different methods have been fabricated by a novel technology and studied in detail by UV-VIS-NIR optical absorption and Raman scattering techniques.
Abstract: In this work the thin polymer films (based on polyvinyl alcohol or carboxymetylcellulose) containing single-wall carbon nanotubes synthesized by different methods have been fabricated by a novel technology and studied in detail by UV-VIS-NIR optical absorption and Raman scattering techniques. The films are prospective as an optical material with a high non-linearity. This property allows using them as ultra-fast saturable absorbers in different laser schemes, especially, in fiber lasers. The optical spectroscopy has been used for optimization of several film parameters: an optical density, a thickness, a level of scattered light and proximity of the film absorption bands to the operation wavelengths of different solid state lasers.

TL;DR: A review of recent studies conducted on carbon nanotube/polymer composites can be found in this paper, where various processing methods for producing these nanocomposites are discussed, in particular melt mixing, solution processing and in-situ polymerization.
Abstract: This paper reviews recent studies conducted on carbon nanotube/polymer composites. Carbon nanotubes are promising new materials for blending with polymers with potential to obtain low-weight nanocomposites of extraordinary mechanical, electrical, thermal and multifunctional properties. The size scale, aspect ratio and properties of nanotubes provide advantages in a variety of applications, including electrostatically dissipative materials; advanced materials with combined stiffness, strength and impact for aerospace or sporting goods; composite mirrors; automotive parts that require electrostatic painting and automotive components with enhanced mechanical properties. The various processing methods for producing these nanocomposites are discussed, in particular melt mixing, solution processing and in-situ polymerization. Some key results are summarized, relating to the mechanical, electrical, thermal, optical and surface properties. Finally, the challenges for the future are discussed in terms of processing, characterization, nanotube availability, nanotube tailoring, and the mechanisms governing the behavior of these remarkable nanoscale composites.

TL;DR: In this paper, the authors discuss the emerging field of mid-infrared frequency comb generation, including technologies based on novel laser gain media, nonlinear frequency conversion and micro-resonators.
Abstract: This Review discusses the emerging field of mid-infrared frequency comb generation, including technologies based on novel laser gain media, nonlinear frequency conversion and microresonators, as well as the applications of these combs in precision spectroscopy and direct frequency comb spectroscopy. Laser frequency combs are coherent light sources that emit a broad spectrum of discrete, evenly spaced narrow lines whose absolute frequency can be measured to within the accuracy of an atomic clock. Their development in the near-infrared and visible domains has revolutionized frequency metrology while also providing numerous unexpected opportunities in other fields such as astronomy and attosecond science. Researchers are now exploring how to extend frequency comb techniques to the mid-infrared spectral region. Versatile mid-infrared frequency comb generators based on novel laser gain media, nonlinear frequency conversion or microresonators promise to significantly expand the applications of frequency combs. In particular, novel approaches to molecular spectroscopy in the 'fingerprint region', with dramatically improved precision, sensitivity, recording time and/or spectral bandwidth may lead to new discoveries in the various fields relevant to molecular science.
