Abstract

See full text

Apparatus and methods of full spatio-temporal characterization of ultrashort pulses from an input pulse-beam source. An interferometer system generates a first, second, third, and fourth replica of the input pulse-beam such that the second replica has a varying delay with respect to the first replica and the fourth replica has a varying delay with respect to the third replica. A reference plane is imaged onto a nonlinear spectral measurement device based upon the first and second replicas, and the reference plane is also imaged onto a wavefront sensitive (WFS) imaging element based on the third and fourth replicas. The signals from the WFS imaging element and the spectral signal are used to compute a pulse temporal spectral profile of the input pulse-beam.
