Product overview

The AA-20DD real-time autocorrelator offers smooth and fast measurement of femtosecond and picosecond pulse duration. The autocorrelatorcan cover several wavelength ranges by using up to 3 interchangeable photodetectors and optics. Input pulse duration varies from 10 fs to 30 psfor 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, as well as via the included LabView drivers. Thesoftware is supplied with the device and comprises several useful tools. The acquired pulse duration data can be visualized, stored or exported toa .txt or .dat file. Autocorrelation function and final FWHM pulse duration in femtoseconds are calculated and displayed in real-time. Moreover, Gaussian or sechA2 fitting options are enabled, intensity function may also be observed. The statistical viewer feature allows the comparison ofdata acquired from several separate pulse measurements.


 

The tiny body of the AA-20DD flawlessly fits any experimental setup with strict space requirements. We also offer an optional fiber input for fastand reliable pulse duration measurement in various optical fibers. Moreover, the autocorrelator in this case still maintains the free-spacemeasurement capability.
