GECO is a scanning autocorrelator designed for pulse duration measurements. It is based on noncollinear second-harmonic generation, producing intensity autocorrelation trace related to the fundamental pulse duration. GECO features a noncollinearity angle adjustment and can be transformed into a collinear setup for measurements down to 10 fs. High resolution is ensured by a delay line with a 0.13 fs/step.

GECO comes with an integrated controller and pulse analysis software. It is capable of generating FROG traces, if an external spectrometer is connected. Software APIs are available for user adaptation.
