Humanity first developed laser technology in May 1960, when the first solid-state ruby laser was built and tested by Theodore Maiman at Hughes Research Laboratories. By the 21st century, lasers had become a multi-billion dollar industry. Civilian applications included reading digital storage disks, reading bar codes, or in handheld devices such as laser pointers. Lasers used in medicine are used for internal surgery and cosmetic applications. In manufacturing, they were used for precision cutting, welding, and other functions. They were also commonly used in various fields in science, especially spectroscopy. Lasers were also used by the military for target identification and weapons guidance systems. All of these uses are presumably just as widespread five centuries later. | Humanity first developed laser technology in May 1960, when the first solid-state ruby laser was built and tested by Theodore Maiman at Hughes Research Laboratories.

The Covenant, on the other hand, has been using laser-based weaponry for far longer. | ||
