Carrier-Envelope Phase(CEP) is an important feature in ultrafast laser spectroscopy. CEP is the phase shift between carrier wave and intensity envelope of laser pulse. In nonlinear optics, full characterization of a laser pulse is critical to determine the moment an electron is ionized from an atomic or molecular system. To obtain absolute CEP , Wen Li’s lab developed a single-shot carrier envelope phase measurement apparatus utilizing the angular streaking technique.
