Usage with chirped Gaussian pulses

[s-nikolaou]

Hello, as a part of my Master thesis I am using this package to calculate harmonic spectra produced by Gaussian pulses, both chirped and unchirped. The way I have been going about it is setting up the vector potential as an integral of the electric laser field, which is a product of the field strength, the Gaussian envelope and a cosine term:

VectorPotential -> Function[t, {Integrate[F*Exp[-1.385*(t/τ)^2]*Cos[ω*t], t], 0, 0}]

This seems to work for unchirped pulses, however when I add the chirp term (i.e. the t^2 term inside the cosine) I get, depending on the values of my FieldParameters, either errors or incorrect spectra. That leads me to believe that my approach is incorrect. If that is the case, what is the correct way to use the package for calculations regarding chirped Gaussian pulses?

Thanks in advance for any help, as well as for sharing this package.
