Abstract

A new technique which determines the complete electric field of ultrashort optical pulses has been experimentally demonstrated. This general technique improves over previous cross-correlation¹ and (interferometric) autocorrelation² techniques in that it determines uniquely and completely the field's phase as well as its amplitude. The technique imposes no requirements on the pulse to be measured and only needs a synchronous probe pulse short enough to resolve all structure of interest.
