Space launches have evoked the same vivid image for decades: bright orange flames exploding beneath a rocket as it lifts off and thunders into the sky. An alternative acceleration system could reshape that vision forever, with rockets leaving their energy source on the ground... or in space. Laser Propulsion in Space: Fundamentals, Technology, and Future Missions takes readers on a comprehensive journey from the theoretical overview of propulsion fundamentals, to reviews of current projects involving high-power CW fiber lasers and energetic mm-wave sources with their ongoing and potential end-use applications in beamed energy propulsion (BEP). Written by experts in the field, this mathematically sound reference text also highlights graphical solutions of equations’ results, as well as case studies with worked-out examples, making this book an invaluable compendium for students, researchers, technology developers and futurists in understanding the promise and challenges of this emerging technology. Covers beamed energy propulsion advances Highlights state-of-the-art BEP applications of LEO debris removal, suborbital and orbital launch, solar system exploration, and interstellar lightsail probes, as well as advances in related photon source technologies and infrastructures Includes opinion sections explaining why we as a technical society should care about each chapter’s topic and the considerably good outcomes that can be achieved with laser engines Is accompanied by a website with video clips and other ancillary materials to enhance insight

First realistic space vehicle design that even remotely has a chance at traversing the vast distances across the "barrier" of outerspace at a velocity faster than light (FTL) space via quantum tunneling on a macroscopic level and return within a reasonable amount of time. Cutting edge technology in propulsion using principles of quantum physics and chirp pulsed amplified (CPA) lasers. The book is written so that it is easily understood by the general public. For deep-space exploration, the design is ideal for exploring new areas of space whereby perhaps dangerous reconnaissance would be required. The manned main body vehicle would safely sit outside the danger zone while the unmanned, remotely controlled vehicles perform the work. There is no need for expensive fuels or propellants whereby travel in space and (mass transit) become feasible. The mass transit application can be viewed as a very high-speed Maglev train only with the exception that there would be no need for tracks except for loading, unloading cargo & passengers.

Pulsed Laser Propulsion For Low Cost High Volume Launch To Orbit written by and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1989 with categories.
Pulsed laser propulsion offers the prospect of delivering high thrust at high specific impulse (500-1000 seconds) from a very simple thruster, using the energy of a remote ground-based laser to heat an inert propellant. Current analyses indicate that payloads of approximately 1 kg per megawatt of average laser power can be launched at a rate of one payload every 15 minutes and a marginal cost of $20 to $200 per kg. A 20 MW entry-level launch system could be built using current technology at a cost of $500 million or less; it would be capable of placing 600 tons per year into LEO. The SDIO Laser Propulsion Program has been developing the technology for such a launch system since 1987. The program has conducted theoretical and experimental research on a particular class of laser-driven thruster, the planar double-pulse LSD-wave thruster, which could be used for a near-term launcher. The double-pulse thruster offers several advantages, including extreme simplicity, design flexibility, and the ability to guide a vehicle remotely by precise control of the laser beam. Small-scale experiments have demonstrated the operation of this thruster at a specific impulse of 600 seconds and 10% efficiency; larger experiments now under way are expected to increase this to at least 20% efficiency. Systems-level issues, from guidance and tracking to possible unique applications, have also been considered and will be briefly discussed. There appear to be no fundamental obstacles to creating, in the next five to ten years, a new low-cost ''pipe-line to space.'' 7 refs., 2 figs., 1 tab.

Laser propulsion uses a large fixed laser to supply energy to heat an inert propellant in a rocket thruster. Such a system has two potential advantages: extreme simplicity of the thruster, and potentially high performance -- particularly high exhaust velocity. By taking advantage of the simplicity of the thruster, it should be possible to launch small (10--1000 kg) payloads to orbit using roughly 1 MW of average laser power per kg of payload. The incremental cost of such launches would be of order $200/kg for the smallest systems, decreasing to essentially the cost of electricity to run the laser (a few times $10/kg) for large systems. Although the individual payload size would be small, a laser launch system would be inherently high-volume, with the capacity to launch tens of thousands of payloads per year. Also, with high exhaust velocity, a laser launch system could launch payloads to high velocities -- geosynchronous transfer, Earth escape, or beyond -- at a relatively small premium over launches to LEO. In this paper, we briefly review the status of pulsed laser propulsion, including proposals for advanced vehicles. We then discuss qualitatively several unique applications appropriate to the early part of the next century, and perhaps valuable well into the next millenium: space habitat supply, deep space mission supply, nuclear waste disposal, and manned vehicle launching.

Laser ablation describes the interaction of intense optical fields with matter, in which atoms are selectively driven off by thermal or nonthermal mechanisms. The field of laser ablation physics is advancing so rapidly that its principal results are seen only in specialized journals and conferences. This is the first book that combines the most recent results in this rapidly advancing field with authoritative treatment of laser ablation and its applications, including the physics of high-power laser-matter interaction. Many practical applications exist, ranging from inertial confinement fusion to propulsion of aerostats for pollution monitoring to laser ignition of hypersonic engines to laser cleaning nanoscale contaminants in high-volume computer hard drive manufacture to direct observation of the electronic or dissociative states in atoms and molecules, to studying the properties of materials during 200kbar shocks developed in 200fs. Selecting topics which are representative of such a broad field is difficult. Laser Ablation and its Applications emphasizes the wide range of these topics rather than - as is so often the case in advanced science – focusing on one specialty or discipline. The book is divided into four sections: theory and modeling, ultrafast interactions, material processing and laser-matter interaction in novel regimes. The latter range from MALDI to ICF, SNOM’s and femtosecond nanosurgery to laser space propulsion. The book arose from the SPIE series of High Power Laser Ablation Symposia which began in 1998. It is intended for a graduate course in laser interactions with plasmas and materials, but it should be accessible to anyone with a graduate degree in physics or engineering. It is also intended as a major reference work to familiarize scientists just entering the field with laser ablation and its applications.

The use of large ground based lasers to radiate power into a rocket engine allows arbitrary choice of propellant and specific impulse. The case of launch of one ton payload from near ground to geosynchronous transfer ellipse appears to be feasible using stacked carbon dioxide repetitive pulse lasers. Atmospheric propagation is enhanced by bleaching out CO2 absorption and using phase correction of the thermal blooming generated we expect that 1 microradian beam spreading can be achieved. The use of pulsed lasers permits an engine based on the laser detonation wave, in which laser energy is efficiently absorbed by inverse Bremsstrhlung in the propellant, which then expands out of the engine and provides thrust. Continuous use costs in the order of $20/lb to GEO are anticipated. (Author).
