Spin force moves NV diamond after illumination with green laser

Graph showing rapid oscillations following illumination with a laser, versus random, atmospheric movements when not illuminated.

By shining a green, 50-milliwatt laser on a diamond with nitrogen-vacancy centers in pulses and measuring its movements with an interferometer, the researchers detected up-and-downward movements (blue line) driven by changes in spin force alone. These movements were much larger than those observed when the laser was off (orange line).
