Step 1

The dispersion parameter (D) is given by the formula: D = -λ^2 * GVD / (2π * c) where λ is the central wavelength, GVD is the group velocity dispersion, and c is the speed of light. Plugging in the values, we have: D = - (800 nm)^2 * 36.163 fs^2/mm / (2π * (3 Show more…

Unchirped Gaussian pulse with a width T = 30 fs at a central wavelength of 800 nm. It propagates through a piece of fused silica, refractive index n = 1.4533, group velocity dispersion (GVD) = 36.163 fs^2/mm. Please calculate the chirp parameter of the output pulse after propagating through 50 cm of fused silica (in the unit of fs^-2).
