WebA chirped Gaussian pulse is well described by Eq. (3.2.15) with C = 5 and = 50 ps. Determine the temporal and spectral widths (FWHM) of this pulse. 3.3 Prove that for an unchirped Gaussian pulse of arbitrary width, the product approximately equals 0.44, where Δ t and Δ ν are the temporal and spectral widths (both measured as FWHM), respectively. WebPropagation of the pulse manipulates it. Dispersive pulse broadening is unavoidable. If 2 is the pulse 2nd-order spectral phase on entering a medium, and k”L is the 2nd-order spectral phase of the medium, then the resulting pulse 2nd-order phase will be the sum: 2 + k”L. A linearly chirped input pulse has 2nd-order phase: 2, 22 /2 in
