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).

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

This book gives an in-depth analysis of the physical phenomena of thrust production by laser radiation, as well as laser propulsion engines, and laser-propelled vehicles. It brings together into a unified context accumulated up-to-date information on laser propulsion research, considering propulsion phenomena, laser propulsion techniques, design of vehicles with laser propulsion engines, and high-power laser systems to provide movement for space vehicles. In particular, the reader will find detailed coverage of: designs of laser propulsion engines, operating as both air-breathing and ramjet engines to launch vehicles into LEOs; Assembly of vehicles whereby laser power from a remote laser is collected and directed into a propulsion engine; and, the laser-adaptive systems that control a laser beam to propel vehicles into orbits by delivering laser power through the Earth's atmosphere. This book is essential reading for researchers and professionals involved in laser propulsion.

The work performed in this 2-year effort involved two tasks: one dealing with issues related to laser energy absorption in a pulsed thruster and the other dealing with issues related to laser energy absorption in a CW thruster. For the pulsed studies, the first year's effort involved theoretical and experimental investigations of the threshold requirements for achieving laser-induced gas breakdown at short wavelengths (

This report describes experimental and analytical studies on pulsed laser propulsion. Volume I describes thruster performance and phenomenology studies. They include. They include theoretical investigations of laser-induced gas breakdown at 10.6 microns and 0.35 microns, the development of a detailed computer model of the quasi-one dimensional nonsteady flow of real gases in the nozzle, and small-scale thruster performance and absorption physics experiments using pulsed CO2 (10.6 microns) and XeF (0.35 microns) lasers. Volume II contains the results of mission analysis studies to evaluate the system requirements of some candidate defense-related missions for pulsed laser propulsion. These studies address the problem of orbit-to-orbit transfer of satellites, as well as the launch of a vehicle from the earth.
