The opening chapter of Nd:YAG Lasers: Technology and Applications aims at reviewing the mechanism of the use of Nd:YAG lasers in vascular lesions, specific indications for its use and treatment efficacy for these specific lesions. Recently, Nd:YAG lasers have also become popular in the treatment of non-vascular lesions. As such, the authors discuss the more recent indications of Nd:YAG lasers. Next, studies on the behaviour of superduplex steel UNS S 32750 when submitted to autogenous welding with Nd:YAG pulsed laser, autogenous welding with Nd:YAG pulsed laser with subsequent refusion processes with Nd:YAG pulsed laser and hybrid welding combining Nd:YAG pulsed laser and GTAW are explored in two situations. The concluding chapter focuses on the applications of Nd:YAG lasers, including in the synthesis of nanocomposites and carbon quantum dots, generating micro- and nano-size emulsions.
The Nd:YAG laser has finally become the multidisciplinary and muitispeciaity tool of the 1980s. Primarily developed for gastrointestinal applications for controlling bleeding, at present it is also used for endoscopic treatment of gastrointestinal tumors, endobronchial cancer, and bladder and gynecological lesions and finding applications in otorhinolaryngology and neurosurgery. De velopment of laser scalpels and focusing head-pieces has now allowed the Nd:YAG laser to be used for open surgical procedures in general and plastic surgery, head and neck surgery, urology, gynecology, dermatology, and neu rosurgery. The rapid development in ceramic technology has led to contact surgery allowing physicians a choice of excision, vaporization, coagulation, incision, or combinations thereof by easily changing probes rather than having to select new laser wavelengths. This technology is rapidly replacing the carbon dioxide laser which currently has no adequate flexible waveguide for fiberoptic en doscopy, cannot be used in a water medium (e.g., bladder), and has poor coagulation properties when compared to the Nd:YAG laser. Future developments may see the Nd:YAG laser even replacing electro cautery in the operating room due to its greater safety and efficacy. Local hyperthermia (laserthermia) with computer control, photodynamic therapy, and ophthalmic applications make the Nd:YAG laser the most exciting tech nological advancement in medicine and surgery for the 1980s.
This comprehensive handbook gives a fully updated guide to lasers and laser systems, including the complete range of their technical applications. The first volume outlines the fundamental components of lasers, their properties and working principles. The second volume gives exhaustive coverage of all major categories of lasers, from solid-state and semiconductor diode to fiber, waveguide, gas, chemical, and dye lasers. The third volume covers modern applications in engineering and technology, including all new and updated case studies spanning telecommunications and data storage to medicine, optical measurement, defense and security, nanomaterials processing and characterization.
The invention of the laser was one of the towering achievements of the twentieth century. At the opening of the twenty-first century we are witnessing the burgeoning of the myriad technical innovations to which that invention has led. The Handbook of Laser Technology and Applications is a practical and long-lasting reference source for scientists and engineers who work with lasers. The Handbook provides, a comprehensive guide to the current status of lasers and laser systems; it is accessible to science or engineering graduates needing no more than standard undergraduate knowledge of optics. Whilst being a self-contained reference work, the Handbook provides extensive references to contemporary work, and is a basis for studying the professional journal literature on the subject. It covers applications through detailed case studies, and is therefore well suited to readers who wish to use it to solve specific problems of their own. The first of the three volumes comprises an introduction to the basic scientific principles of lasers, laser beams and non-linear optics. The second volume describes the mechanisms and operating characteristics of specific types of laser including crystalline solid - state lasers, semiconductor diode lasers, fibre lasers, gas lasers, chemical lasers, dye lasers and many others as well as detailing the optical and electronic components which tailor the laser's performance and beam delivery systems. The third volume is devoted to case studies of applications in a wide range of subjects including materials processing, optical measurement techniques, medicine, telecommunications, data storage, spectroscopy, earth sciences and astronomy, and plasma fusion research. This vast compendium of knowledge on laser science and technology is the work of over 130 international experts, many of whom are recognised as the world leaders in their respective fields. Whether the reader is engaged in the science, technology, industrial or medical applications of lasers or is researching the subject as a manager or investor in technical enterprises they cannot fail to be informed and enlightened by the wide range of information the Handbook supplies.
Nd:YAG laser has recently been widely used for the various vascular applications. This book presents basic vascular and tissue interactions in the Nd:YAG laser treatment of vascular lesions and prepares a guide for clinical use. Lesion diameter, colour, depth and pressure make the basis of the choice of laser parameters. Based on the research presented in this book, it is evident that lasers have been used increasingly as an alternative to surgical methods in the treatment of congenital and acquired vascular lesions. Clinical use of Nd:YAG laser presents a wide range of options to the practising physician in the treatment of different vascular lesions from easy to difficult.
The only introductory text on the market today that explains the underlying physics and engineering applicable to all lasers Although lasers are becoming increasingly important in our high-tech environment, many of the technicians and engineers who install, operate, and maintain them have had little, if any, formal training in the field of electro-optics. This can result in less efficient usage of these important tools. Introduction to Laser Technology, Fourth Edition provides readers with a good understanding of what a laser is and what it can and cannot do. The book explains what types of laser to use for different purposes and how a laser can be modified to improve its performance in a given application. With a unique combination of clarity and technical depth, the book explains the characteristics and important applications of commercial lasers worldwide and discusses light and optics, the fundamental elements of lasers, and laser modification.? In addition to new chapter-end problems, the Fourth Edition includes new and expanded chapter material on: Material and wavelength Diode Laser Arrays Quantum-cascade lasers Fiber lasers Thin-disk and slab lasers Ultrafast fiber lasers Raman lasers Quasi-phase matching Optically pumped semiconductor lasers Introduction to Laser Technology, Fourth Edition is an excellent book for students, technicians, engineers, and other professionals seeking a fuller, more formal introduction to the field of laser technology.
