Available in PDF, EPUB and Kindle. Book excerpt: Volume II of the final report for the Advanced Phased Array Chemical High Energy (APACHE) laser program presents system engineering which specifies requirements, formulates concept- ual designs and performs systems effectiveness analyses for phase conjugate space-based lasers (SBLs). The primary thrust of the systems engineering effort was the formulation of a conceptual design for an APACHE SBL based on the results of detailed modeling, simulation and analysis. The APACHE program also addressed the effectiveness of phase conjugated SBL systems, comparing "conventional" SBLs using active adaptive optics for wavefront correction with phase conjugate SBLs using passive means to both correct wave- fronts as well as combine beams from multiple devices.

Book excerpt: July 2019 Printed in BLACK AND WHITE The Army's Weapon Systems Handbook was updated in July 2019, but is still titled "Weapon Systems Handbook 2018." We are printing this in black and white to keep the price low. It presents many of the acquisition programs currently fielded or in development. The U.S. Army Acquisition Corps, with its 36,000 professionals, bears a unique responsibility for the oversight and systems management of the Army's acquisition lifecycle. With responsibility for hundreds of acquisition programs, civilian and military professionals collectively oversee research, development and acquisition activities totaling more than $20 billion in Fiscal Year 2016 alone. Why buy a book you can download for free? We print this so you don't have to. We at 4th Watch Publishing are former government employees, so we know how government employees actually use the standards. When a new standard is released, somebody has to print it, punch holes and put it in a 3-ring binder. While this is not a big deal for a 5 or 10-page document, many DoD documents are over 400 pages and printing a large document is a time- consuming effort. So, a person that's paid $25 an hour is spending hours simply printing out the tools needed to do the job. That's time that could be better spent doing mission. We publish these documents so you can focus on what you are there for. It's much more cost-effective to just order the latest version from Amazon.com.

Download or read book Laser Surface Interactions written by Rashid A. Ganeev and published by Springer Science & Business Media. This book was released on 2013-10-17 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the interaction of laser radiation with various surfaces at variable parameters of radiation. As a basic principle of classification we chose the energetic or intensity level of interaction of laser radiation with the surfaces. These two characteristics of laser radiation are the most important parameters defining entire spectrum of the processes occurring on the surfaces during interaction with electromagnetic waves. This is a first book containing a whole spectrum of the laser-surface interactions distinguished by the ranges of used laser intensity. It combines the surface response starting from extremely weak laser intensities (~1 W cm-2) up to the relativistic intensities (~1020 W cm-2 and higher). The book provides the basic information about lasers and acquaints the reader with both common applications of laser-surface interactions (laser-related printers, scanners, barcode readers, discs, material processing, military, holography, medicine, etc) and unusual uses of the processes on the surfaces under the action of lasers (art conservation, rangefinders and velocimeters, space and earth explorations, surface engineering and ablation, and others). The scientific applications of laser-surfaces interactions (surface optical nonlinearities, surface enhanced Raman spectroscopy, surface nanostructuring, nanoripples and clusters formation, X-ray lasers and harmonic generation from the surfaces) are discussed from the point of view of the close relations between the properties of surface and matter, which is a cornerstone of most of studies of materials. The novelty of the approach developed in Laser - Surface Interactions is related with the interconnection of scientific studies with numerous applications of the laser-surface interactions separated in different chapters by the ranges of laser intensities. We present most recent achievements in this field. The book provides valuable information for different ranges of reader's preparedness to the laser-related topics (from unprepared readers, to students, engineers and researchers, professionals and academics).
