Autocorrelator

pulseCheck NX

A new generation in short-pulse measurement tools


pulseCheck NX Autocorrelators Cover the Broadest Range of Wavelengths and Pulse Widths


Optics and Detector Technology for UV to IR (200 nm … > 12 µm)

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.

From Ultrashort to Longer Pulses
(5 fs … 500 ps)

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.

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.


Plug & Play and Easy Integration with Network Interface

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.

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.


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.


Intuitive user interface

The pulseCheck NX software has a user-friendly interface with an intuitive layout. It allows the user to focus on relevant data and gives easy access to built-in data analysis. The high-contrast mode option of the graphical user interface (GUI) enables great visibility when using laser safety glasses.


Integrated, comprehensive data analysis

The NX software comes with comprehensive data analysis tools. Integrated functions such as the tracking of measurement and quality parameters save time. Integrated fitting algorithms make it easier to evaluate the data. Operational settings and previously acquired data can be displayed simultaneously to provide context and reference for current measurements.

Optics Sets

A variety of different and exchangeable optics sets cover a wide wavelength range: from UV at 200 nm to mid IR at 12 μm.

 

 

Option FROG measurement for pulseCheck NX

Second Harmonic Generation FROG is the most popular spectrometer-less Frequency Resolved Optical Gating method. The pulseCheck autocorrelators by APE optionally integrate FROG, giving access to complete pulse characterization. This option opens the door to complete spectral and temporal pulse characterization.

Further Features

Collinear and Non-Collinear Measurements

Our autocorrelators support fast switching between collinear and non-collinear measurement modes. The collinear mode – often referred to as interferometric or fringe-resolved mode – provides additional qualitative information about the chirp and the central wavelength of the pulse. In contrast, the non-collinear mode – also referred to as intensity autocorrelation – provides background-free, high dynamic range autocorrelation. Although not background-free, switching between these two modes is even realized with the Mini TPA and TPA optics sets for pulseCheck.

Automatic Phase Matching

Autocorrelators take advantage of phase-sensitive and nonlinear processes and require what is called phase matching. APE’s pulseCheck achieves this software aided for each wavelength range, resulting in precise and fast operation without the need for manual adjustment. Measurements are made even easier by using our TPA detectors, which combine detector and nonlinear optics in a single element. Here, phase matching adjustment is no longer necessary at all.

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.
