Unchirped Gaussian pulse with a width T₁ = 30 fs at a central wavelength of 800 nm, It propagates through a piece of fused silica, reflective index n=1.4533, calculate the the group velocity dispersion (GVD) ? the answer group velocity dispersion (GVD) is 36.163 fs²/mm, but I need the detail expression, so please calculate the group velocity dispersion note: you can use an easier way is to do the derivative numerically as follows f(x + h) − f (x - h) - f'(x) ≈ f(x + h) − 2f(x) + f (x − h) h² here h is a small number 2h
