使用0到f自参考的绝对CEP测量的建议
Proposal for absolute CEP measurement using 0-to-f self-referencing
摘要：
我们展示了如何适应0-f自参考技术，以提供一个Single Shot绝对载波包络相位（CEP）的测量，通过使用由差频产生（DFG）之间的基本脉冲的频谱翼提供的CEP参考。通常，输入脉冲和DFG信号之间的拍频然后提供反馈，利用该反馈来稳定脉冲训练中的CEP滑移。然而，通过简单的扩展，我们可以获得Single Shot绝对CEP测量。成功依赖于具有良好特征的输入脉冲，以及通过非线性晶体使用精确的传播模型-这些使我们能够构建实验测量与光脉冲CEP之间的映射。
英文摘要：
We show how to adapt a 0-f self-referencing technique to provide a single shot absolute Carrier Envelope Phase (CEP) measurement by using the CEP reference provided by difference frequency generation (DFG) between the spectral wings of the fundamental pulse. Usually, the beat between the input pulse and the DFG signal then provides feedback with which to stabilize the CEP slip in a pulse train. However, with a simple extension we can get a single shot absolute CEP measurement. Success relies on having well characterized input pulses, and the use of accurate propagation models through the nonlinear crystal -- these enable us to construct a mapping between the experimental measurement and the CEP of the optical pulse.
