摘要
文章对在Matlab环境中实现FROG脉冲迭代算法进行了理论分析,给出了详细的矩阵数学模型推导过程。在此基础上,根据飞秒脉冲测量需求,在Matlab中编写了GUI用户界面,实现了对FROG行迹的重建和标定。采用该GUI,对实际的飞秒脉冲进行了在线测量,重建后的FROG行迹和标定后的FROG行迹吻合,可直接获取测量中的迭代次数、迭代误差、飞秒脉宽、谱宽等关键信息,可以直接应用到FROG脉宽测试仪的工程化设计中。
In this paper, the theoretical analysis of the FROG pulse iterative algorithm in matlab environment is presented, and a detailed mathematical model of the matrix is given. The GUI is designed in matlab according to the femtosecond pulse measurement needs, It realized the reconstruction and calibration of FROG tracks. The actual femto- second pulse were measured online using the software. The measurement results show that reconstructed FROG trace and calibrated FROG trace are consistent. We can get some key parameters in the measurement, such as the number of iterations, the iterative error, the femtosecond pulse width, the width of the spectrum and so on. And the GUI can be used into the enginee red design of the FROG width tester.
