The APE PulseCheck autocorrelator is a simple, versatile and user-friendly autocorrelation system offering a wealth of features for discerning pulse diagnostics.
The PulseCheck is the industry leader in ultrafast pulse-width measurement, covering pulses from 5fs to 500ps and 200nm to >12μm.
The pulseCheck offers easy-to-use plug & play capability via USB. In addition, the pulseCheck can be easily integrated into automated test and measurement environments with an Ethernet connection (SCPI over TCP/IP). And all this is possible without the need for an additional PC. The pulseCheck can also be controlled directly from any location via a network connection.
APE meets the growing need for maximum functionality and flexibility with the modular concept on which the pulseCheck autocorrelator series is based. Thus, Optics sets to upgrade the wavelength range or FROG capability can be added any time.
A wide variety of professional applications can be covered with various detector types and optics sets. Photomultiplier (PMT) detectors are highly sensitive and are ideal for pulse measurements at low pulse energies. Photodiode detectors, on the other hand, are perfect for measuring lasers with high peak power. In combination with highly efficient optics, our detectors pave the way for measurements over an wide wavelength spectrum from 200 nm to > 12 μm.
Various pulseCheck configurations can be adapted to the individual needs of pulse duration measurement. The measurement of extra long pulse durations up to 500 ps is possible with pulseCheck SM.
