Its measurement principle is the following: it is transforming the temporal shape of the pulse into a spatial shape which can be analyzed by a spatial detector. A beam splitter is separating the analyzed beam, a set of mirrors and optical delay line length is generating a temporal shift on one beam. The two beams are then recombined in the focal plane of a focusing lens. The intensities of the two beams are I(t) and I(t-τ), where t is the temporal optical shift between the beams. A doubling crystal is placed at the lens focal plane, where the second harmonic of the incident beams is created. This is why it is a so-called “second order” autocorrelator. The intensity of the second harmonic beam is proportional to the product of the I(t) and I(t-τ). The second harmonic signal is recorded with a slow response time detector which temporal response is given by the autocorrelation function of I(t). Assuming a Gaussian pulse shape, the pulse half maximum temporal width is given by : Δτ = Δτ (autoco) /√2 where Δτ(autoco) is the autocorrelation width at half maximum. A full supervision single software allows display of the autocorrelation trace I(t).
