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
OMAC Laser 300 been tested on the second machine. This machine was being constructed alongside three other Laser 300s, together representing the first four of thirty aircraft that Omac hoped to build by the end of 1987. The third prototype (and first production machine) flew on 29 July 1987 and certification was now expected by May 1988. By now, production of the redesigned Laser 300 was running one year behind schedule, and the projected cost of the airplane had risen from $US 550,000 to $875,000, albeit for a more capable aircraft. The aircraft was displayed at the NBAA show in Dallas, Texas in
