Book Synopsis Advancement of Selective Laser Melting by Laser Beam Shaping by : Tim Marten Wischeropp
Download or read book Advancement of Selective Laser Melting by Laser Beam Shaping written by Tim Marten Wischeropp and published by Springer Nature. This book was released on 2021-11-30 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective Laser Melting (SLM), also referred to as Laser Powder Bed Fusion (L-PBF), offers significant advantages for the manufacturing of complex, high-quality parts. However, its market share is still small compared to conventional manufacturing technologies. Major drawbacks hindering an industrial ramp-up are low productivity, high part costs and issues with quality and reproducibility. Comprehensive research has been done to overcome these challenges, but little attention has been paid to addressing them by optimizing the laser beam profile. Therefore, the author examines the effect of the laser beam profile on the productivity and process stability through both numerical and experimental investigations. The results show clear advantages an optimized laser beam profile offers.

Shealy to produce the first in-depth account of beam shaping applications and design. Laser Beam Shaping Applications details the important features of beam shaping and exposes the subtleties of the theory and techniques that are best demonstrated through proven applications. In chapters contributed by prominent, active leaders in their respective specialties, the book discusses applications in lithography, laser printing, optical data storage, stable isotope separation, adaptive mirrors, and spatially dispersive lasers. The contributors share major insights, knowledge, and experience, reveal the advantages of the technologies, and include extensive references to the literature. The book concludes with a summary of beam shaping theory and techniques as well as the history of the field. Providing practical expertise, Laser Beam Shaping Applications is an extremely helpful guide to improving current laser processes, optimizing application-specific technologies, and advancing future development in the field.

The book provides essential scientific and technical information to researchers and engineers already working in the field as well as students and young scientists planning to work in the area in the future. Lasers found application in materials processing practically since their invention in 1960, and are currently used widely in manufacturing. The main driving force behind this fact is that the lasers can provide unique solutions in material processing with high quality, high efficiency, high flexibility, high resolution, versatility and low environmental load. Macro-processing based on thermal process using infrared lasers such as CO2 lasers has been the mainstream in the early stages, while research and development of micro- and nano-processing are becoming increasingly more active as short wavelength and/or short pulse width lasers have been developed. In particular, recent advances in ultrafast lasers have opened up a new avenue to laser material processing due to the capabilities of ultrahigh precision micro- and nanofabrication of diverse materials. This handbook is the first book covering the basics, the state-of-the-art and important applications of the dynamic and rapidly expanding discipline of laser micro- and nanoengineering. This comprehensive source makes readers familiar with a broad spectrum of approaches to solve all relevant problems in science and technology.

Book Synopsis A Practical Guide to Handling Laser Diode Beams by : Haiyin Sun
Download or read book A Practical Guide to Handling Laser Diode Beams written by Haiyin Sun and published by Springer. This book was released on 2015-02-20 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the reader a practical guide to the control and characterization of laser diode beams. Laser diodes are the most widely used lasers, accounting for 50% of the global laser market. Correct handling of laser diode beams is the key to the successful use of laser diodes, and this requires an in-depth understanding of their unique properties. Following a short introduction to the working principles of laser diodes, the book describes the basics of laser diode beams and beam propagation, including Zemax modeling of a Gaussian beam propagating through a lens. The core of the book is concerned with laser diode beam manipulations: collimating and focusing, circularization and astigmatism correction, coupling into a single mode optical fiber, diffractive optics and beam shaping, and manipulation of multi transverse mode beams. The final chapter of the book covers beam characterization methods, describing the measurement of spatial and spectral properties, including wavelength and linewidth measurement techniques. The book is a significantly revised and expanded version of the title Laser Diode Beam Basics, Manipulations and Characterizations by the same author. New topics introduced in this volume include: laser diode types and working principles, non-paraxial Gaussian beam, Zemax modeling, numerical analysis of a laser diode beam, spectral property characterization methods, and power and energy characterization techniques. The book approaches the subject in a practical way with mathematical content kept to the minimum level required, making the book a convenient reference for laser diode users.

Book excerpt: The resonator can be considered the real heart of any laser system, the key element that determines the properties of laser radiation, including mode structure or temporal and spatial characteristics. The theory of different laser types has been well-developed in the last few decades of the 20th century, starting with the pioneering papers of Fox, Li, Body and Gordon. But today, due to the development of new types of lasers (fibre, diode), new optical elements (adaptive mirrors, phase conjugation techniques, graded phase correctors), the development of optical technology, and new needs for industrial lasers, novel types of resonators are under investigation.

Book Synopsis Coherent Laser Beam Combining by : Arnaud Brignon
Download or read book Coherent Laser Beam Combining written by Arnaud Brignon and published by John Wiley & Sons. This book was released on 2013-11-13 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser beam combining techniques allow increasing the power of lasers far beyond what it is possible to obtain from a single conventional laser.One step further, coherent beam combining (CBC) also helps to maintain the very unique properties of the laser emission with respect to its spectral and spatial properties. Such lasers are of major interest for many applications, including industrial, environmental, defense, and scientific applications. Recently, significant progress has beenmade in coherent beam combining lasers, with a total output power of 100 kW already achieved. Scaling analysis indicates that further increase of output power with excellent beam quality is feasible by using existing state-of-the-art lasers. Thus, the knowledge of coherent beam combining techniques will become crucial for the design of next-generation highpower lasers. The purpose of this book is to present the more recent concepts of coherent beam combining by world leader teams in the field.

Book Synopsis Ultrashort Pulse Laser Ablation of Bulk Materials Using Shaped Laser Beams by : Dmitriy Mikhaylov
Download or read book Ultrashort Pulse Laser Ablation of Bulk Materials Using Shaped Laser Beams written by Dmitriy Mikhaylov and published by Cuvillier Verlag. This book was released on 2021-06-24 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: High precision, high quality, and high throughput of ultrashort pulse laser ablation of bulk material are the most demanded properties that are required to let this process technology compete with other micro-machining techniques. Previous attempts to increase volumetric ablation rates of ultrashort pulse laser processes were based on the increase of fluence or pulse repetition rates. They run into limitations mainly set by the occurrence of bumpy surfaces due to overheating of bulk material. In this work, the potential of laser beam shaping for the enhancement of ablation rates is studied systematically for the first time. The question regarding the physically shortest possible process time for ablation of 2.5D-structures by means of an ultrashort pulse laser is answered using a heat conduction model, which is extended by the ability to consider spatially shaped beams. The strategy of laser beam stamping is implemented in a novel optical setup and proven both theoretically and experimentally to have a great potential for increasing ablation rates.
