Laser Propulsion for Space Propulsion Applications

Hideyuki Horisawa

Abstract

This is a review of laser propulsion for space propulsion applications by today including a range of specific impulses of 200 ~ 5000 s, momentum coupling coefficients of 0.1~10 kN/MW, and thrust efficiencies of over 100% due to exothermic effects of high-energy propellants, such as GAP. Formulation of momentum generation and some examples of propulsion systems were introduced.
