Measuring Ultrashort Optical Pulses
Ultrafast optics has changed dramatically in the last twenty years, driven by new laser sources, as well as new methods of manipulation and measurement for broadband coherent optical fields. In this article we address the means and technologies that enable experimental characterisation of short electromagnetic pulses, indicating the general principles involved, how these have been implemented in various approaches, and how the most popular methods encode the temporal electric field of a short optical pulse in the measured signal and extract the field reliably from the data. We provide a more detailed design for one of the popular methods, SPIDER.
