Longman Dictionary of Contemporary English
The Collaborative International Dictionary
laser \laser\ n. [acronym from Light Amplification by Stimulated Emission of Radiation: ca. 1955.] A device which produces an intense, usually narrow, monochromatic beam of coherent light; called also optical maser. It has various forms, and is used in various applications in science and technology. The beam is produced by boosting the majority of the electrons in specific radiation-absorbing atoms in a medium into a higher energy level, from which they are stimulated by their own emitted radiation to drop back synchronously to their lower energy level, and emit light which is in phase (coherent).
Syn: optical maser.
Douglas Harper's Etymology Dictionary
1960, acronym for "light amplification by stimulated emission of radiation," on pattern of 1955 MASER. A corresponding verb, lase, was coined 1962.
Etymology 1 n. 1 A device that produces a monochromatic, coherent beam of light. 2 A beam of light produced by such a device; a laser beam. 3 A laser printer. vb. 1 To cut with a #Noun 2 (context sports English) To throw with laser-like precision Etymology 2

n. an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light [syn: optical maser]
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 coherence also allows a laser beam to stay narrow over great distances ( collimation), enabling applications such as laser pointers. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light. Temporal coherence can be used to produce pulses of light as short as a femtosecond.
Among their many applications, lasers are used in optical disk drives, laser printers, and barcode scanners; DNA sequencing instruments, fiber-optic and free-space optical communication; laser surgery and skin treatments; cutting and welding materials; military and law enforcement devices for marking targets and measuring range and speed; and laser lighting displays in entertainment.
The International Laser Class sailboat, also called Laser Standard and the Laser One is a popular one-design class of small sailing dinghy. According to the Laser Class Rules the boat may be sailed by either one or two people, though it is rarely sailed by two. The design, by Bruce Kirby, emphasizes simplicity and performance. The dinghy is manufactured by independent companies in different parts of the world, including LaserPerformance Europe (Americas and Europe), Performance Sailcraft Australia (Oceania) and Performance Sailcraft Japan.
The Laser is one of the most popular single-handed dinghies in the world. As of 2012, there are more than 200,000 boats worldwide. A commonly cited reason for its popularity is that it is robust and simple to rig and sail in addition to its durability. The Laser also provides very competitive racing due to the very tight class association controls which eliminate differences in hull, sails and equipment.
The term "Laser" is often used to refer to the Laser Standard (the largest of the sail plan rigs available for the Laser hull). However, there are two other sail plan rigs available for the Laser Standard hull and a series of other "Laser"-branded boats which are of completely different hull designs. Examples include the Laser 2 and Laser Pico. The Laser Standard, Laser Radial and Laser 4.7 are three types of 'Laser' administered by the International Laser Class Association.
The laser's hull is made out of GRP, Glass Reinforced Plastics. the deck has a foam layer underneath for strength.
A laser is a device which generates a coherent beam of light.

Laser was a debit card scheme in Ireland. The Laser scheme was maintained and operated by Laser Card Services Ltd., a not-for-profit body owned by four leading financial institutions in Ireland and overseen since 2008 by the Oversight Unit of the Central Bank. The scheme was launched in 1996 and in 2010 there were almost 3 million Laser Cards in circulation. 195 million transactions worth almost €11.2 billion were carried out on those cards in 2009. From 2007, the financial institutions which had issued Laser Cards began to replace them with Visa or MasterCard debit cards. Laser cards were withdrawn from the market on February 28 2014.
