(a) Calibration of delay line through interferometric fringes and stability analysis of all-reflective delay line measured with a He-Ne laser \((\lambda\,=\,632\) nm) over time. (b) Normalized histogram of path delay fluctuation. (c) Experimental and theoretical linear autocorrelation signals. (d) Measured (red) and Retrieved (blue) spectra through first-order interferogram. (e) Experimental SHG non-linear autocorrelation signal using BBO. (f) Experimental and theoretical autocorrelation traces based on Fraunhofer diffraction theory for split profile of the beam for positive delay range (0–60 fs).
