Real-time SPIDER: ultrashort pulse characterization at 20 Hz.
We present an implementation of spectral phase interferometry for direct electric-field reconstruction (SPIDER) which characterizes ultrashort optical pulses in the spectral or temporal domain at a rate of 20 Hz. This apparatus was used in real-time as a diagnostic tool to optimize our 1 kHz regeneratively amplified laser system for the shortest duration pulses.
