The APE PulseCheck High-Contrast Autocorelator reveals temporal information of pre-/post-pulses and pedestals.
High contrast measurements with the Autocorrelator pulseCheck Type 2 provide information about how far in time and intensity the main pulse is accompanied by pre-pulses, post-pulses and pedestals.
High contrast measurements with the Autocorrelator pulseCheck SM Type 2 autocorrelator provide information about how far in time and intensity the main pulse is accompanied by pre-pulses, post-pulses and pedestals.
With a high dynamic range of 10^7, the pulseCheck SM Type 2 is ideally suited for the characterisation of high-intensity, high-repetition-rate laser pulses, such as the used in material processing or in ultra-high intensity light-matter interaction experiments
