弹道导弹和巡航导弹是高技术战争中的主要威胁, 对弹道导弹最有效的防御是助推段拦截。首先总结了美国机载激光计划失败的原因和经验教训, 然后评述和分析了无人机载激光**反导的概念、优势、研究计划和现状, 以及存在的问题和面临的挑战。最后, 讨论和分析了用于助推段拦截的二极管抽运碱金属激光器和相干合成光纤激光器的原理、特点、最新进展和技术挑战。

Ballistic and cruise missile are the major threat in high technology war, the most efficient defense for ballistic missile is the boost phase interception. First of all, the failure reason and the lessons learned of US air borne laser project are summarized.Then the concept, superiority, research project and current status, as well as the problems and the challenges of anti-missile UAV-borne laser weapon are reviewed and analyzed. Finally, the principle, characteristics and recent progress and technical challenges of the diode pumped alkali laser and fiber combining laser used in the boost phase interception are discussed and analyzed.
