The SPIDER (Spectral Phase Interferometry for Direct Electric field Reconstruction) system provides precise phase-amplitude measurement of ultrashort laser pulses. The device is widely used for on-line tuning of amplifier systems. The device is used to measure spectral phase, spectral intensity and temporal intensity. It also displays an autocorrelation function.

    The principle of operation is based on spectral shearing interferometry. The spectral phase property is reconstructed from a spectral interferogram registered by a CCD. The other CCD records spectral amplitude of the input pulse. The phase-amplitude characteristic in time domain is obtained by Fourier transformation of the spectral phase-amplitude characteristic. The reconstruction algorithm used is linear and non-iterative.

    The SPIDER features a USB connection with acquisition and analysis Windows software. The unit has a built-in two-channel spectrometer for spectra registration and a CCD camera for easier alignment at low repetition rates.
