Abstract: aser propulsion is a new propulsion technology raised in the early 70’s when both laser technology and astronautics and aeronautics technology had been well developed. Both the limitation of combustion temperature in chemical propulsion and the disadvantage of lower ratio of thrust to mass in nuclear propulsion can be overcome by using laser propulsion.Its specific impulse can reach 20000 N. s/kg,and,the ratio of thrust to mass is typical as that of the chemical propulsion. Introduction.fundamental theory and technology. applications and existing problems of laser propulsion were reported in the paper.
