The AA-10DD real-time autocorrelator offers smooth and fast measurement of femtosecond and picosecond pulse
duration. Different models of the autocorrelator cover several wavelength ranges, with the AA-10DDM model combining
the ranges by using 3 interchangeable photodetectors and optics. Two separate ranges can also be covered upon request.
Input pulse duration ranges from 10 fs to 6 ps for easy monitoring of different laser systems, especially femtosecond and
picosecond oscillators (for amplifier monitoring please see our ASF-20 single-shot autocorrelator).
The device features USB interface and can be easily hooked up to a PC with Windows OS. The software is supplied
with the device and comprises several useful tools. The acquired pulse duration data can be visualized, stored or exported
to a .txt or .dat file. Autocorrelation function and final FWHM pulse duration in femtoseconds are calculated and displayed in
real-time. Moreover, Gaussian or sech2 fitting options are enabled, intensity function may also be observed. The statistical
viewer feature allows the comparison of data acquired from several separate pulse measurements.
The tiny body of the AA-10DD (132x123x118 mm) flawlessly fits any experimental setup with strict space requirements.
We also offer an optional fiber input for fast and reliable pulse duration measurement in various optical fibers.
Moreover, the autocorrelator in this case still maintians the free-space measurement capability.
