Interferometric autocorrelation of sech^2 pulse?

[QUOTE="IcedCoffee, post: 6502178, member: 649038"] Intensity autocorrelation uses second harmonic generation from two non-collinear beam. It cannot resolve the fringes of a multi-cycle pulse. Interferometric autocorrelation uses two collinear beam. The generated second harmonics beam is thus collinear with the two beams, and is affected by interference pattern.
