Dispersion Compensation for a Femtosecond Cr:LiSAF Laser

Abstract
The group delay per length for Cr:LiSAF crystal has been measured, and the result indicates that the refractive index of Cr:LiSAF has a large error. The dispersion of a prism pair is calculated without approximations to be estimated in a large wavelength range. The conditions in which the group delay dispersion and third order dispersion of a femtosecond-Cr:LiSAF-laser cavity are simultaneously zero have been discussed.
