Abstract

Abstract A new method for measuring picosecond transient absorption kinetics is proposed and demonstrated. Generation and transformation of a laser pulse, such that its wavelength changes linearly with time, allows the determination of the time delay after excitation to be made by a simple wavelength measurement. The technique is demonstrated for the case of ground-state bleaching of a dye.
