Splitting a single light pulse into a fast barrage of
rainbow-colored daughter pulses allows scientists to capture movies of complex,
ultrafast physical and biological processes
(April 29, 2015) When
a crystal lattice is excited by a laser pulse, waves of jostling atoms can
travel through the material at close to one sixth the speed of light, or
approximately 28,000 miles/second. Scientists now have a new tool to take
movies of such superfast movement in a single shot.
