Pulse Width Measurement Perfection with the Multitalent from APE
pulseCheck Autocorrelators Cover the Broadest Range of Wavelengths and Pulse Widths
UV to IR
200 nm ... > 12 µm
APE autocorrelators are available with a variety of exchangeable optical sets. This allows sensitive pulse duration measurements over an extremely wide wavelength range. Depending on the pulseCheck configuration, wavelengths in the UV range from 200 nm to the IR range above 12 µm are covered.
From 5 fs to 500 ps
Different pulseCheck configurations can be optimized according to individual pulse width measurement requirements. Extra long pulse durations are possible, for example, with the autocorrelator pulseCheck SM, which measures long pulses over a larger scanning range using fast and highly precise stepper motor technology.
NIST Traceable Calibration
An important requirement for quality assurance systems is the traceability of a measuring instrument to international or national standards. For this reason, all APE autocorrelator models are calibrated to a traceable standard according to NIST specifications (NIST = U.S. National Institute of Standards and Technology).
Each pulseCheck comes with a printed and signed calibration certificate. The calibration can of course be renewed at our premises or by a certified partner at any time.

Three Types of Detectors: PMT, TPA, PD
The three detector types address the need for low noise and enhanced sensitivity in different applications. For pulse measurement with extreme sensitivity and low pulse energy, we recommend our photomultiplier (PMT) detector. Spectrally enhanced photodiodes (PD, TPA), on the other hand, are the ideal choice for measurements requiring sensitivities of a few mW2.
FROG Option for pulseCheck
Complete pulse characterization using FROG is possible for most pulseCheck autocorrelators. FROG allows pulseCheck to measure the spectral and temporal bandwidth and phase. FROG can be upgraded by pulseCheck customers with just a few simple changes to the autocorrelator. With the supplied software, the laser pulse intensity is displayed as a function of time and frequency (wavelength). The result is visualized in the form of the common FROG trace diagram.
