Abstract

Femtosecond optical techniques have contributed greatly to the study of dynamic phenomena in materials. Although femtosecond laser pulse techniques have recently enjoyed great success, the results of frequency-domain experiments, which do not require ultrashort laser pulse technology, have been no less exciting. We have developed a tunable-laser-induced grating technique which provides femtosecond temporal resolution^1-4 and have applied this method to the study of ultrafast relaxation processes in liquids.
