Abstract (en)
[origin: WO2016156391A1] The invention relates to a device for characterising a laser pulse (Pu), comprising at least: - a Fresnel biprism (BPF) that separates an incident laser beam; a detector (CAM) comprising at least one linear semiconductor detector disposed in an overlap zone in which the separated beams interfere and generate a trace by absorption of two photons of at least two beams separated by the Fresnel biprism, said generated trace comprising information characterising the laser pulse (Pu); and a computer (K) that processes a signal from the detector (CAM), produced by the generation of the trace, in order to deduce therefrom a laser pulse duration.
