Method and arrangement for the location - and time-resolved interferometric characterization of ultrashort laser pulses

摘要

For location - and sweetening time-resolved interferometric characterization of ultrashort laser pulses, wherein a spatially resolved not - collinear measurement of the autocorrelation function of the first or higher order of beam shaping by means of a matrix of individual elements is carried out in such a way that a local splitting of the beam in a beam - matrix of conical partial beams is carried out, wherein each partial beam the spatially integrated information about the through-radiated partial surface of the matrix, the local resolution is thus determined by the matrix geometry, and through which each partial beam in a particular, to a matrix camera imaged plane in space interference pattern generated an autocorrelation function of the first order, or by using a non-linear interactions in a suitable medium supplies a correspondingly higher order, so that coherence time or pulse duration of individual laser pulses or sequences of a plurality of laser pulses as a function of the location can be determined.
