Laser Laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently". Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial
Laser Chess Laser Chess Laser Chess is a two-player computer game from 1987, modeled as a board game with chess-like pieces, most of which have mirrored surfaces, and one of which is a laser cannon. "Laser Chess" first appeared in "Compute!'s Atari ST Disk & Magazine" in 1987, written in Modula-2, winning the $5,000 first prize in a programming competition held by the magazine. Ports of the game written in BASIC and machine language were published in the June 1987 issue of "Compute!" Magazine for the Amiga, Commodore 64, Apple II, and Atari 8-bit family as type-in programs.
