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.

Advances in continuous systems, pulsed systems, mode-locked pulses, and the amplification of short pulses are dealt with in detail. This is done by giving an extensive treatment of relevant molecular physics, gas kinetics, excitation and relaxation processes, and laser physics pertinent to CO2. It also provides a thorough theoretical background of specific technologies used in various devices. Many numerical values of physical constants and accurate spectroscopic data of CO2 isotopes are included.
Download or read book Gas Lasers written by Masamori Endo and published by CRC Press. This book was released on 2018-10-03 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers with a gaseous active medium offer high flexibility, wide tunability, and advantages in cost, beam quality, and power scalability. Gas lasers have tended to become overshadowed by the recent popularity and proliferation of semiconductor lasers. As a result of this shift in focus, details on modern developments in gas lasers are difficult to find. In addition, different types of gas lasers have unique properties that are not well-described in other references. Collecting expert contributions from authorities dealing with specific types of lasers, Gas Lasers examines the fundamentals, current research, and applications of this important class of laser. It is important to understand all types of lasers, from solid-state to gaseous, before making a decision for any application. This book fills in the gaps by discussing the definition and properties of gaseous media along with its fluid dynamics, electric excitation circuits, and optical resonators. From this foundation, the discussion launches into the basic physics, characteristics, applications, and current research efforts for specific types of gas lasers: CO lasers, CO2 lasers, HF/DF lasers, excimer lasers, iodine lasers, and metal vapor lasers. The final chapter discusses miscellaneous lasers not covered in the previous chapters. Collecting hard-to-find material into a single, convenient source, Gas Lasers offers an encyclopedic survey that helps you approach new applications with a more complete inventory of laser options.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The series “Clinical Approach and Procedures in Cosmetic Dermatology” intends to be a practical guide in Cosmetic Dermatology. Procedures in cosmetic dermatology are very popular and useful in medicine, indicated to complement topical and oral treatments not only for photodamaged skin but also for other dermatosis such as acne, rosacea, scars, etc. Also, full-face treatments using peelings, lasers, fillers and toxins are increasingly being used, successfully substituting or postponing the need for plastic surgeries. Altogether, these techniques not only provide immediate results but also help patients to sustain long-term benefits, both preventing/treating dermatological diseases and maintaining a healthy and youthful skin. Throughout this series, different treatments in Cosmetic Dermatology will be discussed in detail covering the use of many pharmacological groups of cosmeceuticals, the new advances in nutraceuticals and emerging technologies and procedures. This volume addresses the most important physical approaches in cosmetic dermatology, disclosing their uses and advantages. Here are discussed in detail the applicability of lasers and other lights, photodynamic therapy, radiofrequency, ultrasound and transepidermal drug delivery.

Download or read book The use of CO and CO2 lasers to detect pollutants in the atmosphere written by Robert T. Menzies and published by . This book was released on 1970 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several spectral coincidences between CO laser emission lines and infrared absorption lines of oxides of nitrogen have recently been observed. Using existing infrared spectroscopy data, we predict additional spectral coincidences; the Q-switched CO laser emits certain lines which overlap SO2 absorption lines, and certain frequency doubled CO2 laser lines overlap NO and CO absorption lines. Other spectral overlaps involving the CO2 laser have been reported elsewhere. Based on such coincidences remote sensing of these atmospheric constituents can be accomplished by observing resonant absorption, thermal emission, or fluorescence. The authors discuss sensitivities for each of these methods, using data on line strengths and pressure broadened line widths. Wide band heterodyne receivers offer high sensitivity when they can be used; our discussion included the use of this type of receiver system.
