Abstract
The photonic laser propulsion is a new propulsion concept, which uses the thrust amplification generated by multiple momentum exchange and photon energy recycling through photon oscillation in external cavity composed of two HR mirrors. The basic theory of the propulsion concept was introduced; the production mechanism of thrust was analyzed and theory modeling was derived. Finally, several typical working parameters (laser parameters, environment parameters and cavity parameters) were set to calculate the theory thrust value. The study results indicated that in condition that all incident photons totally attenuate in cavity without leaping, 1kW laser power, mirror reflectivity 0.99999 and cavity length 10m, the maximum amplification factor 500000 and maximum photon thrust 0.333 N could be achieved, satisfying the needs of space missions.
