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 33):
The system for measuring the duration, the temporal profile and the spectrum of an ultrashort laser pulse according to  claim 29 , wherein the imaging spectrometer includes another mirror-based achromatic optical system configured to form an image of the inlet slot on the detector, the other mirror-based achromatic optical system comprising a spherical mirror illuminated with an incidence angle lower than 3 degrees, and another mirror configured to separate a reflected optical beam from an incident optical beam on said spherical mirror.
