Features

  • Measures pulse duration in 10 fs – 20 ps range
  • Single set of optics for 500 – 2000 nm range
  • Integrated controller and computer

Overview

Operation of GECO autocorrelator 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 means of a magnetic linear positioning stage, providing fast, reliable motion with <0.15 fs resolution.

GECO can acquire a full intensity autocorrelation trace of 10 fs to 20 ps pulses and covers the full 500 nm to 2000 nm wavelength range. GECO features noncollinearity angle adjustment and can be simply transformed to a collinear setup, allowing the performance of interferometric autocorrelation measurements which are useful for pulses in the 10 fs range. Both arms of the autocorrelator have the same dispersion parameters for the most accurate results.

GECO comes with a convenient pulse-analysis software, providing straightforward pulse duration measurements. A computer is integrated inside the autocorrelator thus communications are handled via TCP/IP protocol which ensures a simple trouble-free installation. Software and hardware are also capable of generating FROG traces, provided that an external spectrometer is connected to the fiber coupler. Software APIs are available for custom user adaptations.
