Title: Method and apparatus for determining wave characteristics using constrained interactions of waves

Abstract

A frequency resolved optical gating (FROG) system receives an ultrafast laser pulse as the “unknown wave” input to the system. The FROG system preferably generates a spectrogram (FROG trace) of the input pulse using a polarization gate, second harmonic generation or other FROG geometry. The system or method preferably analyzes the spectrogram using constrained outer products and principal component generalized projections to find characteristics of the unknown wave such as intensity and phase. Examples of constrained outer products include outer products that incorporate an external constraint such as spectral information or an internal constraint such as a relationship between the probe and gate components derived from the unknown wave.
