摘要
通用原子(航空系统)公司高能激光器得到了高能液体激光区域防御系统(HELLADS)计划的经费支持,目前已发展到第3代系统,并通过了美国政府验收。首先对HELLADS计划相关信息进行了梳理,分析了其产生背景、研制阶段、支持经费和相关技术进展。其次详细研究了通用原子公司高能激光器的系统结构、技术路线、抽运方式、技术特点和性能指标。通过综合分析可知,通用原子公司第3代高能激光器模块采用紧凑的锂离子电池提供电力,输出功率为75kW,光束质量β<2,电光效率接近30%,模块尺寸为1.3m×0.4m×0.5m,重量/功率比为4kg/kW,持续运行时间超过30s,适合于安装在各种小型战术平台上。最后评述了该激光器输出功率定标放大的技术途径,探讨了其后续发展方向。
The high-energy laser(HEL) system proposed by General Atomics Aeronautical System,Inc.(GA-ASI) has been developed to the third generation system,which supported by high energy liquid laser area defense system(HELLADS)program and approved by U.S.government recently.Firstly,HELLADS program is reviewed.Some information,such as background,development phases,funds,relative technology developments and so on,is introduced.Secondly,system structure,technical route,pumping mode,technical characteristics and performance indexs of HEL of GA-ASI are studied in detail.Compact lithium ion battery is used as power of the third generation of HEL.The output power is 75 kW,beam quality is β<2,electrical to optical efficiency is nearly 30%,module size is 1.3m×0.4m×0.5m,weight/power ratio is 4kg/kW and continuous running time is more than 30s.The third generation of HEL is suitable for installation on all kinds of small tactical platform.Finally,the technical approach to amplify output power calibration of the laser is reviewed,and the future development direction of the laser is discussed.
