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 anacronym that originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.
Zhores Ivanovich Alferov was a Soviet and Russian physicist and academic who contributed significantly to the creation of modern heterostructure physics and electronics. He shared the 2000 Nobel Prize in Physics for the development of the semiconductor heterojunction for optoelectronics. He also became a politician in his later life, serving in the lower house of the Russian parliament, the State Duma, as a member of the Communist Party from 1995.
Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Photonics is closely related to quantum electronics, where quantum electronics deals with the theoretical part of it while photonics deal with its engineering applications. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
Stereoscopy is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from Greek στερεός (stereos) 'firm, solid', and σκοπέω (skopeō) 'to look, to see'. Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope.
Theodore Harold Maiman was an American engineer and physicist who is widely credited with the invention of the laser. Maiman's laser led to the subsequent development of many other types of lasers. The laser was successfully fired on May 16, 1960. In a July 7, 1960, press conference in Manhattan, Maiman and his employer, Hughes Aircraft Company, announced the laser to the world. Maiman was granted a patent for his invention, and he received many awards and honors for his work. His experiences in developing the first laser and subsequent related events are recounted in his book, The Laser Odyssey, later being republished in 2018 under a new title, The Laser Inventor: Memoirs of Theodore H. Maiman.
A laser lighting display or laser light show involves the use of laser light to entertain an audience. A laser light show may consist only of projected laser beams set to music, or may accompany another form of entertainment, typically musical performances.

The Technology and Engineering Emmy Awards, or Technology and Engineering Emmys, are one of two sets of Emmy Awards that are presented for outstanding achievement in engineering development in the television industry. The Technology and Engineering Emmy Awards are presented by the National Academy of Television Arts and Sciences (NATAS), while the separate Primetime Engineering Emmy Awards are given by its sister organization the Academy of Television Arts & Sciences (ATAS).
Audience scanning is when a laser lighting display is directed towards its audience. Although this is preferred for many laser effects such as tunnels, it is potentially dangerous due to the high levels of laser radiation exposed to the eyes of audience members.
The Themed Entertainment Association (TEA) is an international non-profit association that represents creators, developers, designers and producers of themed entertainment. It is also noted for its THEA Awards, which were founded in 1995 and are distributed annually in a range of themed entertainment categories.
Ivan Dryer is generally considered to be the father of the commercial laser light show industry. He is the founder of the world's first continuously running laser entertainment, known as Laserium.
Laser color television, or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display. The systems work either by scanning the entire picture a dot at a time and modulating the laser directly at high frequency, much like the electron beams in a cathode ray tube, or by optically spreading and then modulating the laser and scanning a line at a time, the line itself being modulated in much the same way as with digital light processing (DLP).

A laser projector is a device that projects changing laser beams on a screen to create a moving image for entertainment or professional use. It consists of a housing that contains lasers, mirrors, galvanometer scanners, and other optical components. A laser projector may contain one laser light source for single-color projection or three sources for RGB full color projection.
A solar-pumped laser is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium. This type of laser is unique from other types in that it does not require any artificial energy source. There is even a hypothetical megastructure called a stellaser which uses a star as both the power source and the lasing medium.
