Paper Abstract

Frequency-Resolved Optical Gating (FROG) and its variations are the only techniques available for measuring complex pulses without a well-characterized reference pulse. We study the performance of the FROG generalized-projections (GP) algorithm for retrieving the intensity and phase of very complex ultrashort laser pulses in the presence of noise. Also, we show that a highly simplified version of FROG, GRENOUILLE, can easily measure visible pulses. By tuning a thick crystal, it can cover the entire visible spectrum, which is typically generated from commercial Optical Parameter Amplifications (OPAs)
