The authors of an earlier paper [ Opt. Lett. 32, 3558 (2007) ] reported two “ambiguities” in second-harmonic-generation frequency-resolved optical gating (FROG). One ambiguity is simply wrong—a miscalculation. The other is well known and easily avoided in simple well-known FROG variations. Finally, the authors’ main conclusion—that autocorrelation can be more sensitive to pulse variations than FROG—is also wrong.
