美国高能激光定标放大计划进展分析

Development analysis of American high energy laser scaling initiative

  • 摘要: 高能激光器性能直接决定了激光定向能的毁伤能力和打击射程,为此美国相继启动多项计划,以研制出高功率、高效、紧凑、轻量化,用于战场的坚固型激光器。2019年,启动了激光器定标放大计划(high energy laser scaling initiative,HELSI),制定出最新的国家级激光放大路线图。首先介绍美国HELSI计划的启动背景、研究内容和实施阶段,其次分析HELSI计划第一阶段300 kW的研究进展,最后评述HELSI计划进展的后续影响。综合分析可知,目前洛·马公司的光谱合成光纤激光器技术在第一阶段率先胜出,不仅获得陆军300 kW作战光源的订单,而且还首先获得HELSI计划第二阶段500 kW的研制合同;HELSI计划的进展,使导弹防御局(missile defense agency,MDA)重新重视用于拦截助推段弹道导弹的定向能武器;HELSI计划支持了4种技术路线进行竞争发展,不过未来何种技术路线会最终胜出并部署在战场上,还需要加强先期论证,突破“技术迷雾”。

     

    Abstract: Performance of high energy laser (HEL) directly determines the damage ability and strike range of laser directional energy, and the United States has launched a series of plans to develop high-power, high-efficiency, compact, lightweight and robust lasers for battlefield. In 2019, the high energy laser scaling initiative (HELSI) was proposed, and the latest national laser amplification route was formulated. Firstly, the background, research contents and implementation stages of this HELSI were introduced. Secondly, the research progress of 300 kW in the first stage of HELSI was analyzed. Finally, the subsequent influences of HELSI progress was reviewed. Comprehensive analyses show that the Lockheed has won the first stage by its spectrally combined fiber laser technology, not only obtaining production orders of 300 kW HEL of US Army, but also entering the second stage of HELSI to get development contract of 500 kW HEL firstly. The progress of HELSI has made missile defense agency (MDA) pay more attention to laser weapons used to intercept boost-phase ballistic missiles. HELSI supports four technical approaches of HEL for competitive development. However, which one will eventually be deployed on the battlefield in the future needs to be strengthened the early research and break through the technical fog.
