Abstract

Solid-state lasers offer unique qualities in terms of flexibility, robustness, efficiency, and wavelength diversity. For these reasons, they are nowadays irreplaceable tools in many scientific and industrial applications. The engineering of new materials, the advances in photonics technologies, and the increasing demand for speed, cleanliness, and high-precision in industrial processes contribute to propel the research in this exciting and quickly developing field. Despite the impossibility to cover all the aspects of this very diversified topic in a single publication, this Special Issue "Solid State Lasers Materials, Technologies and Applications" offers an interesting insight into some of the latest developments in this field. Comprehensive review papers describe the state of the art of highly doped fiber lasers and amplifiers, deep-ultraviolet generation, and laser welding under vacuum with high-power lasers. Research articles present the latest results on picosecond pulse amplification, mid-infrared laser sources, parametric down-conversion modules, and coherent beam combining. Heavy-industry applications, such as laser welding and laser cladding, are also addressed.

Abstract

Nanostructuring of materials is a task at the heart of many modern disciplines in mechanical engineering, as well as optics, electronics, and the life sciences. This book includes an introduction to the relevant nonlinear optical processes associated with very short laser pulses for the generation of structures far below the classical optical diffraction limit of about 200 nanometers as well as coverage of state-of-the-art technical and biomedical applications. These applications include silicon and glass wafer processing, production of nanowires, laser transfection and cell reprogramming, optical cleaning, surface treatments of implants, nanowires, 3D nanoprinting, STED lithography, friction modification, and integrated optics.The book highlights also the use of modern femtosecond laser microscopes and nanoscopes as novel nanoprocessing tools.

Abstract

Today, an individual would be hard-pressed to find any science field that does not employ methods and instruments based on the use of fine focused electron and ion beams. Well instrumented and supplemented with advanced methods and techniques, SEMs provide possibilities not only of surface imaging but quantitative measurement of object topologies, local electrophysical characteristics of semiconductor structures and performing elemental analysis. Moreover, a fine focused e-beam is widely used for the creation of micro and nanostructures. The book's approach covers both theoretical and practical issues related to scanning electron microscopy. The book has 41 chapters, divided into six sections: Instrumentation, Methodology, Biology, Medicine, Material Science, Nanostructured Materials for Electronic Industry, Thin Films, Membranes, Ceramic, Geoscience, and Mineralogy. Each chapter, written by different authors, is a complete work which presupposes that readers have some background knowledge on the subject.

Abstract

Spectroscopy is the study of absorption and emission of electromagnetic radiation due to the interaction between matter and energy that energy depends on the specific wavelength of electromagnetic radiation. This field has proven invaluable research tool in a number of areas including chemistry, physics, biology, medicine and ecology. The spectroscopic field of research is growing day-by-day and scientists are exploring new areas in this field by introducing new techniques. The main purpose of this book is to highlight these new spectroscopic techniques like Magnetic Induction Spectroscopy, Laser-Induced Breakdown Spectroscopy, X-ray Photoelectron Spectroscopy, Low Energy Electron Loss Spectroscopy, Micro- to Macro-Raman Spectroscopy, Liquid-Immersion Raman Spectroscopy, High-Resolution Magic Angle Spinning (HR-MAS) Nuclear Magnetic Resonance (NMR) Spectroscopy, Injection and Optical Spectroscopy, and Nano Spectroscopy. This book is divided into five sections including General Spectroscopy, Advanced Spectroscopy, Nano Spectroscopy, Organic Spectroscopy, and Physical Spectroscopy which cover topics from basic to advanced levels which will provide a good source of learning for teaching and research purposes.

Abstract

Optoelectronics - Advanced Materials and Devices is a second edition following the initial Optoelectronics - Materials and Techniques book published in 2011 as part of the InTech collection of international works on optoelectronics. Optoelectronics, as the discipline devoted to the study and application of electronic devices that emit, detect, and otherwise control light, has widely proliferated globally and enabled many of today's modern conveniences. Because of this ubiquity, new applications and novel optical phenomena continue to drive innovation. Accordingly, as with the first book of the collection, this book covers recent achievements by specialists around the world. The growing number of countries participating in this endeavor including now Brazil, Canada, China, Egypt, France, Germany, India, Italy, Japan, Malaysia, Mexico, Moldova, Morocco, Netherlands, Portugal, Romania, Saudi Arabia, South Korea, Taiwan, Ukraine, USA, and Vietnam as well as joint participation of the US and Moldova scientists in edition of this book and writing one of its Chapters testify to the unifying effect of science. An interested reader will find in the book the description of properties and applications employing organic and inorganic materials, such as different polymers, oxides and semiconductors, as well as the methods of fabrication and analysis of operation and regions of application of modern optoelectronic devices.

Abstract

Laser ablation refers to the phenomenon in which a low wavelength and short pulse (ns-fs) duration of laser beam irradiates the surface of a target to induce instant local vaporization of the target material generating a plasma plume consisting of photons, electrons, ions, atoms, molecules, clusters, and liquid or solid particles. This book covers various aspects of using laser ablation phenomenon for material processing including laser ablation applied for the deposition of thin films, for the synthesis of nanomaterials, and for the chemical compositional analysis and surface modification of materials. Through the 18 chapters written by experts from international scientific community, the reader will have access to the most recent research and development findings on laser ablation through original research studies and literature reviews.

Abstract

The book Quantum Cascade Lasers is divided into two sections. More specifically, in Section 1, the calculations on the band structure of cascade lasers and on the electronic band structure of QCL (e.g., transfer matrix technique, finite element method, and variational method, among others) under the existence of an applied electric field are presented. Moreover, a detailed investigation of electrical and optoelectronic properties of multiple-quantum-well structure is carried out. Furthermore, a theoretical study on the intensity noise characteristics of quantum-cascade lasers under the external noncoherent optical injection is carried out. This section ends with an important description on growth methods for QCLs and the possibility of developing GaN-based QCLs among other materials. A few applications of cascade laser structures like power amplification and THz applications are presented, among others, in Section 2. The THz QCL design and fabrication toward the high-temperature and large-average output power operations for the real applications are described. Furthermore, the importance of the power amplification and coherent combination techniques to improve the output power maintaining the single-mode operation is presented.
