一种空气呼吸脉冲激光动力发射器已被提出作为传统化学发射系统的替代方案。通过对脉冲喷气发动机、冲压发动机和火箭飞行模式下的推力建模，计算了脉冲激光推进从地面到地球同步轨道(GEO)的轨道，并估算了发射成本。结果表明，与传统的化学发射器相比，脉冲激光发射器每1兆瓦的束功率可将0.096公斤有效载荷转移到地球同步轨道，并且需要2,800次分区发射才能弥补其激光发射器的成本。
An air-breathing pulse laser powered launcher has been proposed as an alternative to conventional chemical launch systems. The trajectory from the ground to Geosynchronous Earth Orbit (GEO) by pulse laser propulsion is calculated by modeling the thrust during pulsejet, ramjet and rocket flight modes, and the launch cost is estimated. The results show that the pulse laser powered launcher can transfer 0.096 kg payload per 1 MW beam power to GEO, and 2,800 divisional launches of a payload are necessary to redeem the cost of its laser transmitter compared with conventional chemical launchers.
