摘要
为充分利用亚皮秒紫外激光器的大能量、超短脉宽的紫外激光输出特性, 配套建立了激光惯性约束聚变(ICF)诊断设备性能指标的标定平台。标定平台具备激光能量测量、光传输延迟、光束分割与等比递减、序列光脉冲产生器等功能, 可为相关诊断设备提供结构支撑和高真空度的运行环境。通过机械与光学设计完成了平台各部件的研制, 并利用该平台对X射线二极管的响应时间、X光条纹相机的扫速、X射线分幅相机的动态范围等指标进行了标定。结果表明, 该标定平台与亚皮秒紫外标定源的匹配度良好, 可实现多种诊断设备性能指标的精密标定。
Abstract
In order to make full use of output characteristics of high energy, ultrashort pulse width of sub-picosecond ultraviolet lasers, a calibration platform of laser inertial confinement fusion(ICF) diagnostic equipment is established. The calibration platform has such functions as laser energy measurement, optical transmission delay, beam splitting and geometric decline, and sequential optical pulse generator, which can provide the structural support and high vacuum operating environment for the relevant diagnostic equipment. The mechanical and optical design is developed in all parts of the platform, and the platform is used to calibrate the X-ray diode response time, X-ray streak camera sweep speed, X-ray framing camera dynamic range and so on. The results show that the calibration platform matches the sub-picosecond ultraviolet calibration source well, and can achieve precise calibration of various diagnostic equipments.
