This book was released on 2013-08-31 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber laser technology is attracting a great deal of attention due to its numerous applications in fields as diverse as micromachining, biology and medical sciences or telecommunications and its potential as a substitute for solid-state lasers in industrial and technological applications. Fiber lasers are also exciting from the scientific point of view as they are an excellent platform to further study and understand nonlinear optical phenomena. In this chapter, we review the impact of nano-materials, such as graphene and carbon nanotubes, in advancing fiber laser technology. Both graphene and carbon nanotubes present a highly nonlinear optical response, with a high third order susceptibility and saturable absorption. Here, we discuss how these properties can be used to achieve pulse operation using a technique known as mode-locking and how these two materials compare to other mode-locking mechanisms in terms of their ability to achieve pulse operation, the stability of the mode-locked lasers and their long-term reliability.

Book excerpt: In this thesis, several novel devices for fiber laser are proposed and demonstrated. The first type of device is based on modal interference in non-adiabatic fiber tapers. Using such tapers, we demonstrate a simple technique to tune the wavelength of an all-fiber erbium-doped laser. Next, we systematically investigate the use of non-adiabatic fiber tapers for sensing purposes. As a result of this investigation, we have built and characterized several simple and sensitive sensors for highly accurate measurements of strain, temperature, and refractive index. Another class of devices investigated in this dissertation is based on micro-cavities. We propose and demonstrate, for the first time, the use of high-Q micro-spherical resonators as feedback mirrors for fiber lasers. The advantages of these new"mirrors"include compactness, low cost, tunability of the reflection coefficient, and an extremely narrow reflection bandwidth. We demonstrate single-frequency and Q-switched fiber lasers based on micro-spherical mirrors. The next natural step in the development of fiber-lasers involves the phenomenon of mode-locking. For this purpose, we developed a novel type of saturable absorber based on a fiber-taper embedded in a carbon nanotube/polymer composite material (FTECntPC). Subsequently, mode-locking was successfully demonstrated in an erbium-doped fiber laser using the aforementioned FTECntPC saturable absorber. We have thoroughly investigated the dynamics of passively mode-locked fiber lasers that incorporate the FTECntPC saturable absorber. With this new saturable absorber we have been able to obtain the highestpulse energies that have been generated to date directly from a soliton all-fiber laser. In addition, with the help of the novel saturable absorber, we have been able to build and analyze the first bi-directional passively mode-locked fiber laser.

This book was released on 2013-08-31 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single-walled carbon nanotubes (SWCNTs) possessing outstanding linear and nonlinear optical properties are utilized as saturable absorbers (SAs) for passive mode-locking of different bulk solid-state lasers in a wide spectral range between 0.8 and 2μm. To overcome some of the limitations and drawbacks of currently available saturable absorbers, diverse carbon nanotubes and techniques for fabrication of single-walled carbon nanotube saturable absorbers (SWCNT-SAs) are investigated. In this chapter, we discuss various manufacturing procedures and essential characteristics of SWCNT-based passive mode-locking devices, and review recent demonstrations of passively mode-locked solid-state lasers employing different types of SWCNT-SAs.

This book was released on 2017-09-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a series of contemporary techniques and their combinations used for CNTs solubilization, from physical to chemical and biological, applying inorganic and organic compounds, as well as some metal complexes. In some cases, successive steps can be applied, for instance the use of low and high-weight surfactants, or mineral acid treatment for creation of –OH and –COOH groups and their further interaction with organic molecules. Each discussed method leads to an improvement of CNT solubility, frequently a considerable one. The formed dispersions can be stable for long periods of time, from several weeks to some months, and they sometimes even remain stable after centrifugation. Several special studies have been carried out in the areas of influence of solvent and light on CNTs dispersibility, combinations and abilities of surfactants, CNT cytotoxicity, etc. Applications of solubilized CNTs are discussed in this book as well.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes belong to new nanomaterials and have been known for almost 20 years, but their history is somewhat lengthier. They have been identified as promising candidates for various applications.High-temperature preparation techniques are conventional techniques for the synthesis of carbon nanotubes using arc discharge or laser ablation, but today these methods are being replaced by low-temperature vapor deposition techniques, since orientation, alignment, nanotube length, diameter, purity, and density of carbon nanotubes can be precisely controlled. The synthesis of carbon nanotubes by chemical vapor deposition on catalyst arrays leads to nanotube models grown from specific sites on surfaces. The controlled synthesis of nanotubes opens up interesting possibilities in nanoscience and nanotechnologies, including electrical, mechanical and electromechanical properties and devices, chemical functionalization, surface chemistry and photochemistry, molecular sensors, and interfacing with moderate biological systems.Carbon nanotubes are used in many applications due to their unique electrical, mechanical, optical, thermal, and other properties. Conductive and high-strength composite materials, energy saving and energy conversion devices, sensors, visualization of field emissions and sources of radiation, means for storing hydrogen, and nanoscale semiconductor devices, probes, and interconnections are some of the many applications of carbon nanotubes.
