Calculation of crystal length

  1. Nov 25, 2017 #1
    • Member warned that the homework template must be used
    Hey,

    The question sounds like this: I have 100 fs 400 nm pulse passing through the CaF2 crystal. After passing, it gets twice wider (200 ps). What is the length of the crystal?

    Can anyone share the equation which would help me to calculate this?

    Thank you in advance!

    The dispersion?

    n = 1.4419 @ 400nm

    That's the index of refraction, not it's dispersion.
