Autocorrelator



pulseCheck Autocorrelators Cover the Broadest Range of Wavelengths and Pulse Widths


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.

UV at 200 nm to IR at 12 µm

APE provides a selection of exchangeable Optics Sets, ranging from UV at 200 nm to IR at 12 µm, for sensitive measurements across an extremely broad wavelength region.

From < 10 fs up to 400 ps

The various pulseCheck configurations can be optimized accordingly to suit your individual pulse width measurement needs. Extra-long pulse durations are accessible with pulseCheck SM, which utilizes fast and highly precise stepping motor technology to measure long pulses across a larger scan range.

FROG Option for pulseCheck

Most of the pulseCheck autocorrelators by APE optionally integrate FROG and give access to complete pulse characterization. FROG enables  pulseCheck to measure the spectral and temporal bandwidth and phase with just a few adjustments to the autocorrelator.

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.

Collinear and Non-Collinear Measurements

pulseCheck allows for fast switching between collinear and non-collinear measurement modes. Collinear, often referred to as interferometric or fringe-resolved mode, provides additional qualitative information about the chirp and central wavelength of the pulse. In contrast, noncollinear mode, also known as intensity autocorrelation, provides a background-free autocorrelation with a high dynamic range. A „hybrid“ of these two modes, collinear intensity autocorrelation, is realized with the TPA Optics Sets for the pulseCheck.

Automatic Phase Matching

Phase-sensitive, nonlinear processes require phase matching for highly efficient Second Harmonic Generation. pulseCheck achieves this fully automatically for any wavelength range, resulting in precise and fast operation with no manual adjustment needed. Because they perform the task of both detector and nonlinear optics, the TPA detectors provides tuning-free operation over a wide wavelength range.

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.
