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 (with time-bandwidth products of up to 100) in the presence of noise. We compare the performance of three versions of FROG: second-harmonic-generation (SHG) FROG, polarization-gate (PG) FROG, and cross-correlation FROG (XFROG).
