Abstract:
Disclosed is a system for measuring the duration, time profile and spectrum of an ultra-fast laser pulse, including a single-shot optical correlator with wavefront division, a non-linear optical crystal arranged so that a first divided wavefront and a second divided wavefront superpose in the non-linear optical crystal, an optical system forming an image of the non-linear optical crystal on a detection system, a filtering device arranged between the non-linear optical crystal and the detection system and configured to detect both a second-order single-shot interferometric autocorrelation trace at the optical double frequency as well as at least one other first-order single-shot interferometric autocorrelation trace at the fundamental optical frequency or a second-order intensimetric trace at the optical double frequency.

Claim (Index 25):
The system for measuring the duration, the temporal profile and the spectrum of an ultrashort laser pulse according to  claim 16 , wherein the detection system includes a camera comprising a first and a second spatially-resolved detection areas and wherein the filtering device includes a spatial filter having at least one first spatial filtering zone and a second spatial filtering zone, the first spatial filtering zone being configured to let through, on the one hand, the direction of propagation of the bisector of the first and second directions and, on the other hand, the first and/or the second direction, to the first detection area, so as to form the second-order single-shot interferometric autocorrelation trace, and respectively, the second spatial filtering zone being configured to selectively let through the direction of propagation along the bisector of the first and the second directions while blocking the first and second directions towards the second detection area, to form the other single-shot autocorrelation trace of the second-order intensimetric type.
