Book Description
This book delves deeply into the real-world technologies behind the ‘directed energy weapons’ that many believe exist only within the confines of science fiction. On the contrary, directed energy weapons such as high energy lasers are very real, and this book provides a crash course in all the physical and mathematical concepts that make these weapons a reality. Written to serve both scientists researching the physical phenomena of laser effects, as well as engineers focusing on practical applications, the author provides worked examples demonstrating issues such as how to solve for heat diffusion equation for different boundary and initial conditions. Several sections are devoted to reviewing and dealing with solutions of diffusion equations utilizing the aid of the integral transform techniques. Ultimately this book examines the state-of-the-art in currently available high energy laser technologies, and suggests future directions for accelerating practical applications in the field.“br>/div

Book Description
Directed Energy Weapons is nothing new to mankind, historically the origination of such weapons falls in centuries ago when first time the famous Greek mathematician, physicist, engineer, inventor, and astronomer Archimedes of Syracuse used different mirrors to collect sunbeams and focusing them on Romans fleet in order to destroy enemy ships with fire. This is known as the Archimedes Heat Ray. Archimedes may have used mirrors acting collectively as a parabolic reflector to burn ships attacking Syracuse. The device was used to focus sunlight onto approaching ships, causing them to catch fire. Of course the myth or reality of Archimedes Heat Ray still is a questionable story, but certain experiments with the help of a group of students from Massachusetts Institute of Technology was carried out with 127 one-foot (30 cm) square mirror tiles in October of 2005 that was focused on a mock-up wooden ship at a range of around 100 feet (30 m). The flames broke out on a patch of the ship, but only after the sky had been cloudless and the ship had remained stationary for around ten minutes. It was concluded the device was a feasible weapon under these conditions.

Book Description
This publication represents the first in a series of DEPS textbooks, handbooks and monographs on topics of Directed Energy. The project from which this work was derived was originally funded by the High Energy Laser Joint Technology Office (HEL-JTO). JTO was established in 2000 for the purpose of developing and executing comprehensive investment strategy for HEL science and technology that would underpin weapons weapons development. The JTO is currently sponsoring 80 programs across industry, academia, and government agencies with a budget of approximately 60 million. The competitively awarded programs are chosen to advance the current state of the art in HEL technology and fill technology gaps, thus providing a broad capability that can be harvested in acquisition programs by the military services. -- Preface.

Book Description
The Navy is developing three new ship-based weapons that could improve the ability of Navy surface ships to defend themselves against missiles, unmanned aerial vehicles (UAVs), and surface craft: the Surface Navy Laser Weapon System (SNLWS), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), previously known as the hypervelocity projectile (HVP). The Navy refers to the initial (i.e., Increment 1) version of SNLWS as HELIOS, an acronym meaning high-energy laser with integrated optical dazzler and surveillance. EMRG could additionally provide the Navy with a new naval surface fire support (NSFS) weapon for attacking land targets in support of Marines or other friendly ground forces ashore. The Department of Defense is exploring the potential for using GLGP across multiple U.S. military services. Any one of these three new weapons, if successfully developed and deployed, might be regarded as a "game changer" for defending Navy surface ships against enemy missiles and UAVs. If two or three of them are successfully developed and deployed, the result might be considered not just a game changer, but a revolution. Rarely has the Navy had so many potential new types of surface-ship air-defense weapons simultaneously available for development and potential deployment. Although the Navy in recent years has made considerable progress in developing technologies for these new weapons, a number of significant development challenges remain. Overcoming these challenges will require additional development work, and ultimate success in overcoming them is not guaranteed. The issue for Congress is whether to approve, reject, or modify the Navy's funding requests and proposed acquisition strategies for these three potential new weapons. Potential oversight questions for Congress include the following: Using currently available air-defense weapons, how well could Navy surface ships defend themselves in a combat scenario against an adversary such as China that has or could have large numbers of missiles and UAVs? How would this situation change if Navy surface ships in coming years were equipped with SNLWS, EMRG, GLGP, or some combination of these systems? How significant are the remaining development challenges for SNLWS, EMRG, and GLGP? Are current schedules for developing SNLWS, EMRG, and GLGP appropriate in relation to remaining development challenges and projected improvements in enemy missiles and UAVs? When does the Navy anticipate issuing roadmaps detailing its plans for procuring and installing production versions of SNLWS, EMRG, and GLGP on specific Navy ships by specific dates? Will the kinds of surface ships that the Navy plans to procure in coming years have sufficient space, weight, electrical power, and cooling capability to take full advantage of SNLWS and EMRG? What changes, if any, would need to be made in Navy plans for procuring large surface combatants (i.e., destroyers and cruisers) or other Navy ships to take full advantage of SNLWS and EMRGs? Given the Navy's interest in HPV, how committed is the Navy to completing the development of EMRG and eventually deploying EMRGs on Navy ships? Are the funding line items for SNLWS, EMRG, and GLDP sufficiently visible for supporting congressional oversight?
