Kramers–Kronig relations, femtosecond pulse, time-domain spectroscopy technique


We have proposed a new method for obtaining the Kramers–Kronig relations based on the analysis of the earlier proposed solution of the wave equation for a dispersion medium [2]. The use of this solution for ultra-wideband (femtosecond) optical signals allowed us to propose a simultaneous measurement method for both n (w) and k (w). The latter is a further development of the time-domain spectroscopy method.
