Peter Epperlein W. Semiconductor Laser Engineering, Reliability and Diagnostics. A Practical Approach to High Power and Single Mode Devices

This reference book provides a fully integrated novel approach to the development of high-power, single-transverse mode, edge-emitting diode lasers by addressing the complementary topics of device engineering, reliability engineering and device diagnostics in the same book, and thus closes the gap in the current book literature. Diode laser fundamentals are discussed, followed by an elaborate discussion of problem-oriented design guidelines and techniques, and by a systematic treatment of the origins of laser degradation and a thorough exploration of the engineering means to enhance the optical strength of the laser. Stability criteria of critical laser characteristics and key laser robustness factors are discussed along with clear design considerations in the context of reliability engineering approaches and models, and typical programs for reliability tests and laser product qualifications. Novel, advanced diagnostic methods are reviewed to discuss, for the first time in detail in book literature, performance- and reliability-impacting factors such as temperature, stress and material instabilities. Further key features include: practical design guidelines that consider also reliability related effects, key laser robustness factors, basic laser fabrication and packaging issues; detailed discussion of diagnostic investigations of diode lasers, the fundamentals of the applied approaches and techniques, many of them pioneered by the author to be fit-for-purpose and novel in the application; systematic insight into laser degradation modes such as catastrophic optical damage, and a wide range of technologies to increase the optical strength of diode lasers; coverage of basic concepts and techniques of laser reliability engineering with details on a standard commercial high power laser reliability test program. Semiconductor Laser Engineering, Reliability and Diagnostics reflects the extensive expertise of the author in the diode laser field both as a top scientific researcher as well as a key developer of high-power highly reliable devices.

J. Davim Paulo Laser in Manufacturing

Generally a laser (light amplification by stimulated emission of radiation) is defined as “a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light from a lasing medium of controlled purity, size, and shape”. Laser material processing represents a great number of methods, which are rapidly growing in current and different industrial applications as new alternatives to traditional manufacturing processes. Nowadays, the use of lasers in manufacturing is an emerging area with a wide variety of applications, for example, in electronics, molds and dies, and biomedical applications. The purpose of this book is to present a collection of examples illustrating the state of the art and research developments to lasers in manufacturing, covering laser rapid manufacturing, lasers in metal forming applications, laser forming of metal foams, mathematical modeling of laser drilling, thermal stress analysis, modeling and simulation of laser welding, and the use of lasers in surface engineering. This book can be used as a research book for a final undergraduate engineering course or as a subject on lasers in manufacturing at the postgraduate level. Also, this book can serve as a useful reference for academics, laser researchers, mechanical, manufacturing, materials or physics engineers, or professionals in any related modern manufacturing technology. Contents 1. Laser Rapid Manufacturing: Technology, Applications, Modeling and Future Prospects, Christ P. Paul, Pankaj Bhargava, Atul Kumar, Ayukt K. Pathak and Lalit M. Kukreja. 2. Lasers in Metal Forming Applications, Stephen A. Akinlabi, Mukul Shukla, Esther T. Akinlabi and Tshilidzi Marwala. 3. Laser Forming of Metal Foams, Fabrizio Quadrini, Denise Bellisario, Erica A. Squeo and Loredana Santo. 4. Mathematical Modeling of Laser Drilling, Maturose Suchatawat and Mohammad Sheikh. 5. Laser Cutting a Small Diameter Hole: Thermal Stress Analysis, Bekir S.
