... Benefits & Technology Optics and Detector Technology 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. Collinear and Non-Collinear Measurements Our autocorrelators support fast switching...

pulseCheck NX The Modular Autocorrelator Pulse Measurement Perfection with the Multitalent from APE The pulseCheck platform grows with your tasks. Suitable for characterizing virtually all ultrafast pulse lasers, APE's pulseCheck autocorrelator covers a wide range of wavelengths and pulse widths. This flexibility is achieved by using interchangeable optics sets, typically consisting of a nonlinear crystal and a dedicated detector module. Exchangeable Optics Sets for wavelength coverage from 200 nm to 12 µm Wide range of sensitivity levels covered with PMT, PD, and TPA High temporal...

Overview Specifications Pulse Width Refresh Rate Depending on scan range, 120 ps/sec Intensity Resolution Delay Resolution Detector Types Electronics Software Connectivity see page 14 pulsecheck SM 2000 for details High Resolution & Strong Processing Performance The advanced system-on-chip based architecture enables measurements with low latency, a high time resolution down to 50 attoseconds and an intensity dynamic range of 18 bit. This allows full access to even the tiniest autocorrelation features.

... Flexibility for your Experiments Maximum Functionality through Modular Design 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. From Ultrashort to Longer Pulses 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. Pulse Width Measurement Range t High...
