pulseCheck SM Type 2 High Contrast Reveals Temporal Information of Pre-/Post-pulses and Pedestals
Revealing Pre-pulses, Post-pulses, Pedestals, Satellites
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 107, the pulseCheck SM Type 2 is ideally suited for the characterization of high-intensity, high-repetition rate laser pulses, such as the used in material processing or in ultra-high intensity light-matter interaction experiments.

Acquisition Software and TCP/IP Standard Software Interface
All models come with an easy to use data acquisition software, allowing for real-time data display. Furthermore, the TCP/IP-based standard software interface by APE makes it straight forward to set up remote control. This allows you, for example, to design your own automated measurement routines. Simply use our protocol templates for rapid configuration with familiar programming languages, including C++, C#, LabVIEW, Python, Matlab, and Ruby.
NIST Traceable Calibration
Laboratories and manufacturers are often faced with systematically establishing an unbroken chain of calibrations to specified references. All APE autocorrelator models are calibrated to a traceable standard in accordance with NIST (U.S. National Institute of Standards and Technology) measurement traceability specifications. A printed and signed calibration certificate is provided with each pulseCheck.
