研制了多功能、高精度的激光参数精密诊断系统，整个诊断系统由基频光诊断模块、三倍频光诊断模块、在线损伤检测模块、开放式频率转换组件以及相应的辅助单元组成，在系统控制软件调度下自动完成频率转换组件前后的光束近场、远场、能量、波前和脉冲波形等激光参数的精密测量以及数据采集、储存和处理，为激光装置负载能力提升和相关关键单元技术的研究提供准确可靠的数据。“,”A multi-functional high-precision comprehensive diagnostic system for laser parameters was developed. The entire diagnostic system was composed of a fundamental frequency laser diagnostic module, a tripled frequency laser diagnostic module, an online optic damage inspection module, an opening frequency conversion unit and corresponding auxiliary units. Under the control of the system software, it can automatically perform accurate measurement, data collection, storage and processing on laser parameters such as near-field, far-field, energy, wavefront and pulse-waveform before and after the laser frequency conversion. This system provides accurate data for improving laser facility load capacity and researching relevant key unit technology.
