Ultrafast Laser & Mirrors (IMAGE)
Caption
The ultrafast laser shoots very short light pulses 80 million times a second at the hybrid perovskite material to determine whether its electrons could be used to carry information in future devices. They split the laser into two beams; the first one hits the film to set the electron spin in the desired direction. The second beam bends through a series of mirrors like a pin ball machine before hitting the perovskite film at increasing time intervals to measure how long the electron held the spin in the prepared direction.
