PulseCheck Type 2 ‘High Contrast’ Autocorrelator

This special autocorrelator provides high-contrast measurements, and therefore reveals temporal information of pre-/post-pulses, pedestals and satellites.

High contrast measurements with the Autocorrelator pulseCheck Type 2 high contrast provide information about how far in time and intensity the main pulse is accompanied by pre-pulses, post-pulses and pedestals.

With a high contrast ratio of > 65 dB, pulseCheck Type 2 High Contrast is ideally suited for the characterization of high-intensity laser pulses, such as those used in material processing or in ultra-high-intensity laser-matter interaction experiments.


  • Wavelength range NIR 700 - 1200 nm (others on request)
  • Measuring intense pulses and their pre-pulses, post-pulses, pedestals
  • High dynamic range measurements
  • Ultra-precise delay resolution
  • Automatic phase matching
  • NIST traceable calibration
  • Ready to use software and USB interface
  • TCP/IP remote control with standardized command set for easy programming



This product could be used for the following applications:

  • characterization of high-intensity laser pulses
  • material processing
  • ultra-high-intensity laser-matter interaction experiments


This product is manufactured by APE GmbH.
