Abstract

A new technique for the measurement of the pulse-width of ultrashort optical pulses has been recently proposed [1]. I argue in this comment that such a technique is unable to get any temporal information on an ultrashort pulse, based on the absence of a time-non-stationary element in the proposed setup.
