Femtosecond Characterization Tool
Interferometric Autocorrelator IAC

The VENTEON | PULSE : FOUR interferometric autocorrelator is a stand-alone tool for precise measurements of pulse durations down to 5 fs - the shortest pulse durations commercially available.
The use of a high-performance piezo-driven translation stage and Nanolayers NANEO ultrabroadband optics guarantee for highly accurate measurements with a dispersion-compensated setup, dispersion balanced interferometer arms and several hundred nanometer optical bandwidth.
Very compact, robust and user-friendly optical setup for direct use with our VENTEON | PULSE : ONE laser family or any other short pulse laser system.

The fully computer-controlled data acquisition and pulse analysis software displays the spectrum, autocorrelation and pulse duration on a single user interface (optional).


Specifications:

  • Characterization range: 5 - 50 fs
  • High-dynamic input range
  • Built-up with NANEO broadband optics
  • Dispersion-compensated setup
  • Dispersion-balanced interferometer
  • Suitable for oscillator and amplifier characterization
  • High-resolution piezo-stage with capacitive measurement system
  • Basic reconstruction software
  • Dimensions 300 mm x 420 mm x 120 mm
  • Weight ~10 kg (~22 lbs)

  • Developed in cooperation with Prof. Thomas Wilhein's group at the Rheinahrcampus Remagen and Prof. Uwe Morgner's group at the Institute of Quantum Optics at the University of Hannover.

  • The high-dynamic input-level range due to the use of a sensitive photomultiplier detector allows for using full oscillator power as well as some percent as input signal.
  • A high-precision piezo-stage with internal capacitive measurement system gives an accurate piezo movement and delay calibration. The positioning signal can be externally accessed directly from the device.
  • The characterization range can be extended up to 300 fs upon request.
  • The compact size includes all optics and control-electronics such as piezo-amplifier, power supply and frequency
  • There is no need for additional equipment despite an oscilloscope and spectrometer.
  • Our optional analysis package includes an USB oscilloscope, spectrometer and complete data-acquisition and pulse characterization software pre-installed on a laptop computer.
