GECO is a scanning autocorrelator designed for pulse duration measurements of systems with ≥ 1 kHz repetition rate. Operation of GECO is based on noncollinear second-harmonic generation in a nonlinear crystal, producing intensity autocorrelation trace directly related to the input beam pulse duration. One arm of the fundamental pulse is delayed by a linear positioning stage, providing fast, reliable motion with 0.13 fs resolution. GECO can acquire a full intensity autocorrelation trace of 10 fs – 20 ps pulses and covers the 500 – 2000 nm wavelength range. GECO features noncollinearity angle adjustment and can be transformed into a collinear setup, allowing the performance of interferometric autocorrelation measurements for pulses in the 10 fs range.

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