Ordinary light could never have made it to the moon mirror and back, whereas laser light did quite easily. Properties of Laser Light The photons of laser light are collimated. In other words, they all travel from the laser in the same direction. Laser light is also coherent, meaning that all the waves in a laser beam have the same wave pattern. These properties make laser light more intense than ordinary light and allow it to travel long distances. Ordinary light waves scatter in all directions from their source.

Once it spots one, the ABL platform—a militarized 747 freighter filled with lasers for ranging, targeting, and attack—will get a lock on the target. When the missile rises above the clouds, the ABL will focus a beam of light 15 inches in diameter on the missile’s skin.
