超快光脉冲载波包络相位的时空耦合

Space-time coupling of the carrier-envelope phase in ultrafast optical pulses

Ido Attia, Eugene Frumker

摘要:

载波包络相位(CEP)在精密频率梳谱、全光原子钟、量子科学与技术、天文学、星载计量学、强场科学等领域中发挥着越来越重要的作用。目前,人们基本上认为CEP是一种严格的时间现象。在这里,我们介绍了一种方法的CEP在空间定义的感兴趣的区域的时空计算。我们发现了一个显着的变化的CEP在折射聚焦元件的焦体积,并准确地计算其值。我们讨论了这一发现的意义和重要性。我们的方法特别适合应用于复杂的,现实世界的光学系统,从而使其特别有用的应用在研究实验室以及在工程的创新设计,依赖于CEP。

英文摘要:

The carrier-envelope phase (CEP) plays an increasingly important role in precise frequency comb spectroscopy, all-optical atomic clocks, quantum science and technology, astronomy, space-borne-metrology, and strong-field science. Hitherto, it has been essentially assumed that CEP is strictly a temporal phenomenon. Here we introduce an approach for space-time calculation of the CEP in the spatially defined region of interest. We find a significant variation of CEP in the focal volume of refracting focusing elements and accurately calculate its value. We discuss the implications and importance of this finding. Our method is particularly suitable for application to complex, real-world, optical systems thereby making it especially useful to applications in research labs as well as in the engineering of innovative designs that rely on the CEP.
