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.

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.

Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

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.

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.
