Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is 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 which is ''coherent''. 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 and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

Laser (debit Card)
Laser was a debit card scheme in Ireland between 1996 and 2014. 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 three 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 Laser cards were withdrawn from the market on 28 February 2014. Use Laser was primarily an electronic point of sale debit card, but could also be used by telephone and internet, at ATMs and to pay regular bills by direct debit. When purchasing goods or services with a Laser card up to €100 cashback could be given to cardholders and this value was simply added to the purchas ...

Atom Laser
An atom laser is a coherent state of propagating atoms. They are created out of a Bose–Einstein condensate of atoms that are output coupled using various techniques. Much like an optical laser, an atom laser is a coherent beam that behaves like a wave. There has been some argument that the term "atom laser" is misleading. Indeed, "laser" stands for "Light Amplification by Stimulated Emission of Radiation" which is not particularly related to the physical object called an atom laser, and perhaps describes more accurately the Bose–Einstein condensate (BEC). The terminology most widely used in the community today is to distinguish between the BEC, typically obtained by evaporation in a conservative trap, from the atom laser itself, which is a propagating atomic wave obtained by extraction from a previously realized BEC. Some ongoing experimental research tries to obtain directly an atom laser from a "hot" beam of atoms without making a trapped BEC first. Introduction The first pul ...

Silphium (antiquity)
Silphium (also known as ''silphion'', ''laserwort'', or ''laser'') is an unidentified plant that was used in classical antiquity as a seasoning, perfume, aphrodisiac, and medicine. It also was used as a contraceptive by ancient Greeks and Romans. It was the essential item of trade from the ancient North African city of Cyrene, and was so critical to the Cyrenian economy that most of their coins bore a picture of the plant. The valuable product was the plant's resin (''laser'', ''laserpicium'', or ''lasarpicium''). Silphium was an important species in classical antiquity, as evidenced by the Egyptians and Knossos Minoans developing a specific glyph to represent the silphium plant. It was used widely by most ancient Mediterranean cultures; the Romans, who mentioned the plant in poems or songs, considered it "worth its weight in denarii" (silver coins), or even gold. Legend said that it was a gift from the god Apollo. The exact identity of silphium is unclear. It was claimed to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Copperfield's Laser Illusion
David Copperfield's laser illusion is an illusion performed by David Copperfield in several magic shows. The magician or his assistant is cut by a "laser" into two or more parts and starts walking. Illusion description As performed during the 2001 TV special ''Copperfield: Tornado of Fire'', Copperfield was "cut in half" by his assistant or assistants, wielding the laser beam. Sparks and flames flew where the beam "hits" his body. Copperfield then demonstrated to the audience that he was truly in two pieces by lowering the top half of his body onto a chair while the lower half of his body (waist down) remained visibly standing. As the finale, Copperfield, still separated from the waist, held on to his legs as he walked and hopped to the front of the stage, where he lifted the upper half of his body onto the bottom half and "re-connected" himself.''Copperfield: Tornado of Fire'', CBS (2001).

Laser (roller Coaster)
''Teststrecke'', meaning Test Track in German, is a portable steel roller coaster owned by the German showman partnership Meyer & Rosenzweig. It was imported from Dorney Park & Wildwater Kingdom in 2008 and generally tours in Germany, with occasional visits to the Netherlands.

The ride was previously named Laser and Colossus. The trains on ''Teststrecke'' are themed to resemble racing cars and are, just like the trains on the Boomerang coaster at the Wiener Prater, designed by SAT Consulting. Each train has a single lap bar to secure riders in their seats. It can operate all three at peak times, but it runs with one when there are no queues. The coaster is portable in th ...

Laser (dinghy)
The Laser is a class of Single-handed sailing, single-handed, one-design dinghy sailing, sailing dinghies using a common hull design with three interchangeable rigs of different sail areas, appropriate to a given combination of wind strength and crew weight. Bruce Kirby (yachts), Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance. The Laser is a widely produced class of dinghies. As of 2018, there were more than 215,000 boats worldwide. It is an international class with sailors in 120 countries, and an Olympic class since 1996. Its wide acceptance is attributable to its robust construction, simple rig and ease of sailing that offer competitive racing due to tight class association controls which eliminate differences in hull, sails, and equipment. The International Laser Class Association (ILCA) defines the specifications and competition rules for the boat, which is officially referred to as the ILCA Dinghy, due to a trademark dispute.
