Abstract
Frequency Resolved Optical Gating (FROG) uses the ultrafast laser pulse to interrogate itself for full characterization; that is, no reference pulse is used to obtain the full intensity and phase of the input ultrafast laser pulse. Crosscorrelation FROG (X-FROG) cross-correlates a known ultrafast laser pulse with an unknown ultrafast laser pulse to characterize the unknown pulse allowing wider wavelength ranges of ultrafast laser pulses as well as more complex ultrafast laser pulses to be characterized. We present a new X-FROG algorithm, based on the principal components generalized projections (PCGP) algorithm that is fast, robust, and simple.
