技术成熟度作为一种重要的评估工具，可为**装备的**采办提供更为全面的决策依据，并有效降低装备研制中的技术风险。简要介绍了国外技术成熟度评价方法，研究了技术成熟度评估在美国舰载激光系统LaWS中的应用。LaWS系统由发射望远镜、作战光源、测距仪、目标跟踪单元、总控子系统等5个子系统组成，在系统开发中，除了少量的定制部件外，大量采用了工业激光器、惯性测量装置、传感器、视频跟踪器等商用器件。回顾了LaWS系统已进行的系列演示试验，分析了每次试验暴露的技术问题及采取的解决途径，评估了各阶段的技术成熟度。最后评述了LaWS系统的研发途径及其战场部署意义。

As an important evaluating method, the technology readiness level (TRL) can provide a better decision-making basis for the defense acquisition of weaponry, and can effectively reduce the technical risk of equipment development. The foreign evaluation methods of technology readiness level were briefly introduced, and the application of technology readiness level in the American ship-based laser system LaWS was studied. The LaWS system consists of five sub-systems such as transmitter-telescope, light source in military operation, diastimeter, target tracking sensor and control system. In the system development, in addition to a small number of custom components, a large number of industrial lasers, inertial measurement devices, sensors, video trackers and other commercial devices are adopted. A series of demonstration experiments were retrospected in LaWS system, the technical problems exposed in each test and the corresponding solutions adopted were analyzed, and the technology readiness level of each stage was evaluated. Finally, the research and development approach and the significance of battlefield deployment were reviewed.
