Spectral Phase Measurement

Avoca SPIDER System - Del Mar Photonics, Inc. (Del Mar Photonics)

Spectral phase interferometry for direct electric-field reconstruction (SPIDER) is one technique that can recover the spectral phase of an input pulse, without needing any reference pulse. SPIDER interferes two pulses which areseparated in time and in frequency, and the resultantinterferogram is read by a spectrometer.
