Book Sharp Focusing of Laser Light

Download or read book Sharp Focusing of Laser Light written by Victor V. Kotlyar and published by CRC Press. This book was released on 2019-10-28 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers will learn in which ways light can be "confined" within a subwavelength region smaller than half a wavelength. Strictly within the focal spot, all degrees of freedom of light interact and manifest themselves in a dramatic way. The size and shape of the focal spot and the magnitude of side-lobes depend on the polarization state alongside phase and amplitude distributions of a light beam. Readers will learn techniques in which inhomogeneously (i.e., azimuthally and radially) polarized optical beams can be focused. In sharp focus, exotic phenomena can occur, including the negative propagation of light and a toroidal optical flow. Throughout the book, the numerical simulation is performed using the rigorous solution of Maxwell’s equations based on a Finite-Difference Time-Domain (FDTD) approach, which makes the results of modeling highly reliable. The photonic components, including optical metasurfaces, discussed in the book have been implemented using state-of-the-art techniques of electron beam writing and reactive ion-beam etching of microrelief. Two chapters are concerned with photonics hot spots, which deal with the control of light by means of optical metasurfaces and the generation of an energy backflow in the region of sharp focus of a laser beam. Another hot topic is diffractive polarization converters implemented as subwavelength diffraction gratings to convert polarization of light. By way of illustration, such converters are shown to perform linear-to-radial or linear-to-azimuthal polarization conversion. The book describes advanced photonic components fabricated by the authors to perform sharp focusing of light, including binary zone plates, binary axicons, a planar photonic crystal lens, diffraction polarization converters, and metalenses. This book is a must-have for individuals and institutions studying cutting edge optics.

Book excerpt: From the New York Times bestselling authors of Sprint comes “a unique and engaging read about a proven habit framework [that] readers can apply to each day” (Insider, Best Books to Form New Habits). “If you want to achieve more (without going nuts), read this book.”—Charles Duhigg, author of The Power of Habit Nobody ever looked at an empty calendar and said, "The best way to spend this time is by cramming it full of meetings!" or got to work in the morning and thought, Today I'll spend hours on Facebook! Yet that's exactly what we do. Why? In a world where information refreshes endlessly and the workday feels like a race to react to other people's priorities faster, frazzled and distracted has become our default position. But what if the exhaustion of constant busyness wasn't mandatory? What if you could step off the hamster wheel and start taking control of your time and attention? That's what this book is about. As creators of Google Ventures' renowned "design sprint," Jake and John have helped hundreds of teams solve important problems by changing how they work. Building on the success of these sprints and their experience designing ubiquitous tech products from Gmail to YouTube, they spent years experimenting with their own habits and routines, looking for ways to help people optimize their energy, focus, and time. Now they've packaged the most effective tactics into a four-step daily framework that anyone can use to systematically design their days. Make Time is not a one-size-fits-all formula. Instead, it offers a customizable menu of bite-size tips and strategies that can be tailored to individual habits and lifestyles. Make Time isn't about productivity, or checking off more to-dos. Nor does it propose unrealistic solutions like throwing out your smartphone or swearing off social media. Making time isn't about radically overhauling your lifestyle; it's about making small shifts in your environment to liberate yourself from constant busyness and distraction. A must-read for anyone who has ever thought, If only there were more hours in the day..., Make Time will help you stop passively reacting to the demands of the modern world and start intentionally making time for the things that matter.

Book Advancement of Selective Laser Melting by Laser Beam Shaping

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.

Book In His Father s Shadow

Download or read book In His Father s Shadow written by Stanley A. Renshon and published by St. Martin's Press. This book was released on 2015-03-10 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a pampered son who showed little promise, to his rise to the presidency, George W. Bush has transformed himself through acts of will and faith. Stanley Renshon examines the psychological transformation of Bush and identifies those pivotal changes that allowed him to achieve success in his personal life and in the political arena, and shows how Bush's personal transformation has come to shape his political policies. The man who battled--and defeated--his own inner demons has become a president determined to battle the demons of terrorism and extremism that prevent democracy from flourishing around the world. This psychological portrait provides a much-needed antidote to prevailing critiques that ridicule Bush's values and policies, as it celebrates his resolve and strong leadership.

Book Self focusing  Past and Present

Download or read book Self focusing Past and Present written by Robert W. Boyd and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-focusing has been an area of active scientific investigation for nearly 50 years. This book presents a comprehensive treatment of this topic and reviews both theoretical and experimental investigations of self-focusing. This book should be of interest to scientists and engineers working with lasers and their applications. From a practical point of view, self-focusing effects impose a limit on the power that can be transmitted through a material medium. Self-focusing also can reduce the threshold for the occurrence of other nonlinear optical processes. Self-focusing often leads to damage in optical materials and is a limiting factor in the design of high-power laser systems. But it can be harnessed for the design of useful devices such as optical power limiters and switches. At a formal level, the equations for self-focusing are equivalent to those describing Bose-Einstein condensates and certain aspects of plasma physics and hydrodynamics. There is thus a unifying theme between nonlinear optics and these other disciplines. One of the goals of this book is to connect the extensive early literature on self-focusing, filament-ation, self-trapping, and collapse with more recent studies aimed at issues such as self-focusing of fs pulses, white light generation, and the generation of filaments in air with lengths of more than 10 km. It also describes some modern advances in self-focusing theory including the influence of beam nonparaxiality on self-focusing collapse. This book consists of 24 chapters. Among them are three reprinted key landmark articles published earlier. It also contains the first publication of the 1964 paper that describes the first laboratory observation of self-focusing phenomena with photographic evidence.

Book A Guided Tour of Light Beams

Download or read book A Guided Tour of Light Beams written by David S Simon and published by Morgan & Claypool Publishers. This book was released on 2016-12-07 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: From science fiction death rays to supermarket scanners, lasers have become deeply embedded in our daily lives and our culture. But in recent decades the standard laser beam has evolved into an array of more specialized light beams with a variety of strange and counterintuitive properties. Some of them have the ability to reconstruct themselves after disruption by an obstacle, while others can bend in complicated shapes or rotate like a corkscrew. These unusual optical effects open new and exciting possibilities for science and technology. For example, they make possible microscopic tractor beams that pull objects toward the source of the light, and they allow the trapping and manipulation of individual molecules to construct specially-tailored nanostructures for engineering or medical use. It has even been found that beams of light can produce lines of darkness that can be tied in knots. This book is an introductory survey of these specialized light beams and their scientific applications, at a level suitable for undergraduates with a basic knowledge of optics and quantum mechanics. It provides a unified treatment of the subject, collecting together in textbook form for the first time many topics currently found only in the original research literature.
