Detailed descriptions of dispersion and how it significantly affects ultrafast laser systems can be found in our Dispersion and Ultrafast Dispersion application notes. The positive chirp, or dispersion, introduced by most optical media in ultrafast systems can be compensated for using optical components, such as highly-dispersive mirrors, that feature negative dispersion. This gives short wavelengths a higher phase velocity than that of long wavelengths, which balances out the positive chirp and compresses the pulse duration.
