Single-shot spectroscopy techniques provide scientists with a new understanding of a mysterious light-driven process. Harold “Doc” Edgerton, the late MIT professor, developed high-speed strobe-flash photography in the 1960s that allowed us to visualize events too fast for the eye — a droplet hit
Now, scientists at MIT and the University of Texas at Austin have for the first time captured snapshots of a light-induced metastable phase hidden from the equilibrium universe by using a suite of advanced spectroscopic tools. They were able to view this transition in real-time by using single-shot spectroscopy techniques on a 2D crystal with nanoscale modulations of electron density.
“The key to this result was the development of a state-of-the-art laser method that can ‘make movies’ of irreversible processes in quantum materials with a time resolution of 100 femtoseconds.” adds Baldini. Adds Nelson, “One of the key challenges is that observing an ultrafast transformation from one electronic order to one that may persist indefinitely is not practical with conventional time-resolved techniques.”The researchers developed a unique method that involved splitting a single probe laser pulse into several hundred distinct probe pulses that all arrived at the sample at different times before and after switching was initiated by a separate, ultrafast excitation pulse.
