Spatio-temporal characterization of intense ultrashort laser pulses
When ultrashort pulses pass through common optical elements such as gratings and thick lenses, they can pick up spatio-temporal couplings (STCs) - nonseparable chromatic aberrations. The main cause of this phenomenon is the inherent feature of ultrashort pulses—their broadband spectrum. STCs increase pulse duration and reduce the intensity at the focus, which will be detrimental for many applicati
