利用带调节滤波器的互相关技术，对频率成分分离良好的超短脉冲进行了相位恢复。本文将该滤波器设计为非平衡光纤马赫-曾德尔干涉仪。利用脉冲整形装置产生1太赫兹间隙的脉冲。然后采用快速相位恢复算法重建这些脉冲。在任何情况下都没有发现相对相位或其他特征的模糊性。
Unique phase retrieval of ultrashort pulses with well-separated frequency components was demonstrated using a cross-correlation technique with a conditioning filter. Here, this filter was designed as an unbalanced fiber Mach–Zehnder interferometer. A pulse-shaping apparatus was used to generate pulses with a 1 THz gap. A fast phase-retrieval algorithm was then employed to reconstruct these pulses. Ambiguities of relative-phase or other characteristics were not found under any circumstances.
