The Interferometric Autocorrelator (IA) can provide very useful information about femtosecond pulse chirp. IA accuracy of the definition pulse duration can be 5-10%. |
Computer registration of the interferometric autocorrelator signal
gives a possibility for the femtosecond pulse full analysis and exact
pulse shape determination.
