Creation of an Ultrafast, Multi-Dimensional Spectroscopic Facility for the Investigation of Optical Limiters

Abstract

A facility for measuring time and wavelength resolved photo-induced absorption spectra based on step-scan fourier transform techniques has been constructed and demonstrated. This facility is now doing measurements on the ms - ns timescales routinely and has been used to investigate photo-induced absorption in organic electron donor-acceptor systems in solution and thin film as well as crystalline inorganic systems. Proof of principle experiments have been performed with a streak camera to extend this method to the ps time scale.
