Download or read book CO2 Lasers Effects and Applications written by W Duley and published by Elsevier. This book was released on 2012-12-02 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2 Lasers: Effects and Applications examines and summarizes the important applications of the device in different areas of study like physics, chemistry, and engineering. In some parts of the book, the reader is assumed to be knowledgeable in university level mathematics or some specialized area in physics or chemistry. The book consists of 10 chapters where the first two establish the general concepts on lasers and CO2 lasers, respectively. Chapter 3 takes the reader further and presents a comprehensive review of optical components for use such as detectors, windows, and mirrors. Because the CO2 laser is mostly used as a heat source, the theory of laser-surface heating is relevant in the discussion. This theory is presented in Chapter 4. Chapters 5 and 6 meanwhile present a summary of observations on cutting, welding, and some related topics. The following chapters discuss the different applications of CO2 lasers in different areas and processes. Some of these applications include in the generation of thermal effect, laser deposition of thin films, spectroscopy, laser photochemistry, and meteorology and communication systems. The text is a good source of reference to both students and scientists in the areas of physics, chemistry, and engineering.

Book Synopsis Lasers in Gynecology by : Gunther Bastert
Download or read book Lasers in Gynecology written by Gunther Bastert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: A synopsis of the use of lasers in gynecology is presented in this book; it is supported by more than 10 years of experience and backed up by studies inthe fields of experimental surgery, technical medicine and clinical gynecology. The authors show how laser-assisted preparation hasbroadened the spectrum of operative possibilities in gynecology. Major points of attention are experimental surgery and basic research, details of application with respect to specific indications, and future potential. Furthermore, the clear definition of the possibilities and limitations of laser technology puts an end to the highly stylized view of a patent wonder divorced from general operative standards. Thereis no doubt that users of laser technology stand on the threshold of a promising development and yet, despite the present elegant applications, thefirst steps to maturity are only now being taken.
Download or read book CO2 Laser Cutting written by John Powell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laser has given manufacturing industry a new tool. When the laser beam is focused it can generate one of the world's most intense energy sources, more intense than flames and arcs, though similar to an electron beam. In fact the intensity is such that it can vaporise most known materials. The laser material processing industry has been growing swiftly as the quality, speed and new manufacturing possibilities become better understood. In the fore of these new technologies is the process of laser cutting. Laser cutting leads because it is a direct process substitu tion and the laser can usually do the job with greater flexibility, speed and quality than its competitors. However, to achieve these high speeds with high quality con siderable know how and experience is required. This information is usually carefully guarded by the businesses concerned and has to be gained by hard experience and technical understanding. Yet in this book John Powell explains in lucid and almost non technical language many of these process wrinkles concerning alignment, cornering, pulsing, water jets, material properties, cutting speeds as well as tricks with surface coating and much much more. It is a book which managers and technicians in laser job shops and laser processing facilities would be foolish not to read.

Book Synopsis Principles and Practice of Lasers in Otorhinolaryngology and Head and Neck Surgery by : V. Oswal
Download or read book Principles and Practice of Lasers in Otorhinolaryngology and Head and Neck Surgery written by V. Oswal and published by Kugler Publications. This book was released on 2014-01-24 with total page 951 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword In this era's informational paradigm, while pondering the considerations to be penned in this foreword, the relevance of a text such as this emerged progressively as the focal point. After all, for years, one established source for accessing large amounts of valuable information had been the Encyclopaedia Britannica, a printed tome, which is no longer relevant. Instant access to the latest scientific information is freely available to all with an internet. So, what can this text provide that cannot be readily accessed? In contemplating given topics, the Editors, as most certainly occurred in this publication, chose clinical authorities to author chapters in their areas of expertise. The experienced clinician often finds such a forum a unique opportunity to reflect on years of knowledge acquisition and then render an insightful discourse on the lineage of his/her current understanding of the topic. On the other side of the coin, the reader instantly acquires a knowledge base, which was validated with an exhaustive literature search and gains the senior authors' perspective of it. A less experienced author will benefit from thoroughly reviewing the currently available science and technology and moreover, gain experience in scientific writing. In the latter scenario the senior author is at once mentor and expert. Under ordinary circumstances, from the concept outline submission to a publisher, the time line to completion of the text is approximately one and a half to two years. Recruiting and assigning authors, awaiting late manuscript submissions and editing are unquestionably time consuming. Yet a passionate, dedicated Editor will take seemingly varied submissions and script them into a worthy finished product. Such was the case with this publication. The end result is a superbly structured text covering most of the concepts relating to the topic in a format that is both logical and intuitive. At the risk of some redundancy, I share with you my thoughts on some of the significant number of new additions and improvements made to this second edition. The chapter on risk management is a welcome contribution. The rationale for the shift in the current decision tree for laryngeal cancer as it relates to macro versus micro margins, improvements in voice quality and the choice of initial therapeutic considerations are appropriately vetted. The rethinking of HPV associated malignancies is a new and most important addition. Zeitels' presentation of angiolytic lasers for benign and malignant pathology is state of the art. I particularly enjoyed reading about lasers and the association with tropical diseases. The chapters on robotic surgery, non-invasive cartilage reshaping and photo-diagnostics puts the latest technical innovation in our discipline into perspective. The excellent illustrations and photographs are a bonus. There are other areas that could be mentioned e.g. paediatrics, however, the aforementioned has more than adequately established the tenor of the text. n their quest to provide a one-stop knowledge base of a reference quality, it is inescapable that the size of the final proof would surpass the typical numbers of between four and five hundred pages for the hard bound volume. Tightening the text by removing some peripheral material would deprive the book its very objective of a reference quality publication. The obvious solution was to present the work in a set of two volumes, and the editors and the publishers have to be congratulated in achieving this seamlessly. The natural anatomical split provides the reader with a convenience of picking up the volume of relevance for the task at hand. An unusual feature is the inclusion of MCQs after each chapter, to serve as a test for recall of knowledge, the result of which can be assessed simply by going back to the chapter! The Editors and the publishers have exploited the now ubiquitous electronic media network to their advantage. Operating on various platforms a dedicated website will complement the book with updates, operative videos, and means of communication to share the knowledge globally. It was the focus of this brief foreword to explore the relevance of this text in the current informational climate. It provides the essential foundation for informed thought on this topic. Agree or disagree with the information contained within, the reader has acquired the knowledge to be able to do such. With this text you will be rewarded for sitting in your most comfortable chair, thumbing through the pages and sensing the new print. Immediately understood will be the time and effort it took to complete a text of this calibre. Read the chapters first that initially appeal to you and then without question you will read the remainder. This book should be in the library of any serious student of the subject. I feel privileged to have been asked to write the foreword. Marshall Strome

This book was released on 2013-12-11 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: In conventional partial resection of parenchymatous organs significant bleeding is one of the main problems, especially in neonates and infants. The patients rapidly lose considerable amounts of their small blood volume. Laser light leads to photo thermal effects in tissue and causes coagulation, drying up, carbonization and evaporization, depending on the temperature. The neodymium Y AG laser emits nonvisible light in the near infrared with a wavelength of l. 0611m. This wavelength implies a relatively deep penetration into the tissue. This laser system, properly a coagulation laser, achieves its cutting effect by its high power density [9]. Because of thermal radiation in all directions, both sides of the section plane are coagulated as a positive side effect. Thus, in parenchymatous organs a combination of resection and sealing of the cut vessels and ducts, up to a limited diameter, is obtained. Laser Instruments We use a neodymium-YAG laser mediLas 2 (MBB-Medizintechnik, D-8012 Ottobrunn, Federal Republic of Germany), wavelength l. 0611m, maximal power output around 110 W (Fig. 1). Normally we prefer to work without tissue contact, Fig. l.
