Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to take this Sellmeier equation,

n^2 (λ)=1+ (B_1 λ^2)/(λ^2-C_1 )+(B_2 λ^2)/(λ^2-C_2 )+(B_3 λ^2)/(λ^2-C_3 )

for which i have several sets of constants for prospective glasses, and convert it into a group delay dispersion graph, with axes of fs^2 vs wavelength.

How do i rearrange the equation above (or convert the resultant graph) into a form i can use to find the GDD for the glasses?

If it's easier, i could use the GVD instead of the GDD.

Thanks!
