Abstract
We investigate, both theoretically and experimentally, the practical use of amplitude and phase pulse shapers to characterize ultrashort optical pulses. Pulse shapers greatly simplify the optical setup required for the SH-FROG and SPIDER measurement techniques, and both methods can even be implemented with a common optical layout. We also introduce, demonstrate, and compare several new interferometric variants of these techniques, which are compatible with a basic setup comprising no more than a pulse shaper, a type I second-harmonic stage, and a spectrometer.
