There is no software for an autocorrelator because it s impossible to determine the intensity or phase from an autocorrelation trace. The autocorrelation doesn t contain enough information to determine these quantities. The FROG trace, on the other hand, does. Of course, as we said above, you can use FROG or GRENOUILLE without the software, and you still have a lot more information than there is in an autocorrelation.
