摘　　要：匹配高系统集成度的半导体二极管激光列阵(DLA)多发光单元特性的高系统集成度外腔工作参数稳定技术,通过拾取外腔形变传感器的响应等运行状态监控参数,经映射处理等处理后,获取控制参数,适时调整基超模运行所需腔体参数等,反馈控制,使DLA稳定运行于基超模。求得系统控制参数与外腔等参数之间的关系,以及建立相应鲁棒控制模型,是随DLA及其应用具体需求设计控制系统的指导基础,实验表明,基于此优化设计的高密外腔形变传感控制系统,可精细传感控制外腔形变,稳定外腔工作参数,改善高集成度激光列阵系统稳定运行于基超模可用性和系统可靠性。To implement novel integrated stability robust control technology （ISRC） in a diode laser array （DLA） system whose emitters are in high density level,the lowest order super-mode will run stably in the system with a high quality. The deformation sensor subsystem for the integrated external cavity will track parameters of the super-modes of the system. With inmapping, end-mapping, add-transforming and so forth, the kernel regulator will execute controlling parameters to guarantee that the lowest order super-mode will run well. The feedback compensation DLA model fuses elements of ISRC effectively to help design the integrated DLA system in engineering. The experiment demonstrates that ISRC makes the quality of laser beam better, and improves the reliability and availability of the integrated PLA system.
