Abstract:
In 1991, when only very roughmeasures of ultrashort laser pulses were available, Rick Trebino’s group developed the first successful device for measuring their precise intensity andphase vs. time, called frequency-resolved optical gating (FROG). Today FROG isthe gold standard of pulse measurement. Since then, his group has solved (orassisted in solving) essentially every pulse-measurement problem, from verycomplex pulses to very weak pulses (a few photons), culminating in clever,practical techniques for measuring the complete spatio-temporal intensity andphase of even complex pulses on a single shot and at a tight focus. Theirtechniques have played key roles in numerous breakthroughs, from attosecondscience to metrology, to coherent control, to light bullets. These surprisinglyeasy-to-use, but powerful devices now measure ultrashort light pulses morecompletely than is possible for cw light, leading to a wide range of likelyimportant future applications, from micro-machining to medicalimaging.
