结果表明

该方案能够准确地测量光学任意波形的幅度和相位。利用门脉冲选通过程含有增益放大的特点

可以实现对微弱信号的测量。

Abstract

In order to investigate the modulation phenomenon of pulse in the time domain and determine its frequency spectrum

an Optical Parametric Amplification-Frequency-Resolved Optical Gating（OPA-FROG）measurement scheme for optical arbitrary waveforms based on optical parametric amplification of crystal is presented in this paper.The program structure is simple and easy to implement.In the MATLAB environment

we use the Principal Component Generalized Projects（PCGP）algorithm to recovery the waveform.The results show that the scheme can achieve an accurate measurement of the amplitude and phase of arbitrary optical waveform.The characteristics of gating process of the gate pulse with gain amplification can realize the measurement of weak signals.
