Abstract
We construct several examples of distinct asymmetric-symmetric pulse pairs with identical
or essentially identical intensity autocorrelations and power spectra. From these examples we
infer that pulse retrieval methods based on these two data sets alone produce ambiguous
solutions. Furthermore, we used the constructed pulse pairs as test cases to assess the degree of
difference in the corresponding interferometric autocorrelations. In several cases we found that
the differences in the interferometric autocorrelations are sufficiently small that they might be
quite challenging to distinguish in a practical experimental context.
