Researchers are developing a new, military-grade"quantum laser" that can cut through fog and operate across long distances.
Conventional lasers work by stimulating electrons in atoms to oscillate in unison. When these electrons move from a high-energy state to a low-energy state, they release a form of light called"coherent light" — light with uniform wavelength and phase. As this light is bounced between mirrors inside the laser device, it is refined into a concentrated laser beam.
