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 22):
The system for measuring the duration, the temporal profile and the spectrum of an ultrashort laser pulse according to  claim 16 , wherein the filtering device includes a spatial filter able to be switched in opening between a first and a second opening, the first opening being configured to let through to the detection system, on the one hand, the direction of propagation of the bisector of the first and second directions and, on the other hand, the first direction and/or the second direction, so as to form the second-order single-shot interferometric autocorrelation trace, and, respectively, the second opening being configured to selectively let through to the detection system the axis of propagation along the bisector of the first and second directions, while blocking the first and second directions to form the other single-shot autocorrelation trace of the second-order intensimetric type.
