We investigate attosecond streaking measurements, where a spectrogram is described by an ensemble of electron wave packets. Such a description may be required for processes more complex than direct photoemission from an isolated atom; an ensemble of wave packets may also be needed to describe the role of shot-to-shot fluctuations or a non-uniform spatio-temporal profile of attosecond light pulses. Under these conditions, we examine the performance of conventional (FROG) analysis of attosecond streaking measurements.
我们研究阿秒条纹测量，其中频谱图由电子波包的集合来描述。对于比孤立原子的直接光发射更复杂的过程，可能需要这样的描述；为了描述逐次测量的涨落或阿秒光脉冲的非均匀时空分布的作用，也可能需要波包的集合。在这些条件下，我们检验了阿秒条纹测量的传统（FROG）分析的性能。
