Abstract :
The use of a free electron laser (FEL) as the power source for transmission from Earth stations to space assets is discussed. Considerations of requirements including net power transmitted, system reliability, system availability, cost, and technical maturity are addressed to determine a reasonable development path to an optimal system. Various applications of transmitted power are examined such as supplementary power to communications satellites, orbit raising through the use of electric and thermal thrusters, supplementary power to manned orbiters and space stations. It is seen that each of these applications leads to different stages of infrastructure development, and that a program following a near optimal development path can lead to a system that has justifiable investments for the services delivered at each stage past the initial technology demonstration.<>
