中文摘要	拍瓦激光参数诊断过程中,为满足单脉冲信噪比测量仪中周期性极化铌酸锂(PPLN)晶体对光束偏振态的要求,皮秒测量平台的光路排布中采用了立体空间分布结构。针对单脉冲信噪比测量仪快速精确的在线准直要求,推导出马达调整的4x4维线性矩阵的数学模型算法,实现皮秒测量平台立体空间激光光路的快速精确准直。实验结果表明,该准直算法能够保证马达调整3次以下,准直时间2 min以内,实现近场准直精度小于0.16 mm,远场调整精度小于0.17mrad。满足信噪比测量对准直精度和准直时间的要求,使得信噪比信号获取成功率由10%提升到90%,保障拍瓦激光信噪比实验结果满足总体要求(大于10~6)。
英文摘要	Measurement platform must exhibit a stereoscopic space distribution in diagnostic systems for petawatt lasers to meet the requirement of a periodically poled lithium niobate (PPLN) crystal for light polarization in single-pulse contrast measuring instrument. A mathematical model of a 4D linear matrix is proposed to achieve rapid and accurate beam alignment in picosecond measurement platform. In the petawatt experiments, the alignment algorithm ensures that the near-field and far-field accuracy is less than 0.16 mm and 0.17 mrad, respectively. The motor is adjusted less than three times, and the corresponding elapsed time is in 2 min. The mathematical model meets measurement requirements for alignment accuracy and time. The pulse contrast of the petawatt lasers is obtained from the model. The pulse acquisition probability of the contrast measuring instrument reaches 90% from 10%, to guarantee that the experimental result of pulse contrast can meet the general requirement (more than 10~6).
