Few-cycle laser pulses: extreme light sources for extreme physics
Today, intense laser pulses containing only a few oscillations of the electric field are a key element in many important areas of science and technology, from ultrafast spectroscopy to high-harmonic generation and attosecond physics. The measurement of such ultra-broadband pulses is often as challenging as the generation process itself. This talk will present a brief overview of some representative few-cycle pulse sources, from octave-spanning laser oscillators to higher energy pulse compressors, that have been optimized and fully characterized using the newly developed dispersion-scan technique, a robust and simple method that enables the simultaneous measurement and compression of ultrashort pulses. Several key aspects of this technology and its potential to tackle fundamental processes in Nature will also be discussed.
