rotating mirror laser
1laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
2Laser engraving — is the practice of using lasers to engrave or mark an object. The technique can be very technical and complex, and often a computer system is used to drive the movements of the laser head. Despite this complexity, very precise and clean… …
3Mirror galvanometer — A mirror galvanometer A mirror galvanometer is a mechanical meter that senses electric current, except that instead of moving a needle, it moves a mirror. The mirror reflects a beam of light, which projects onto a meter, and acts as a long,… …
4Laser level — See US Patent 5836081. Invented by Steve Orosz. UsageThere are several type of laser levels. There are levels with a rotating motor that creates the illusion of a line.Then there are the newer levels with a fixed lens to create the line. Invented …

7Laser video projector — A laser video projector takes a video signal and modulates a laser beam in order to project a raster based image. The systems work either by scanning the entire picture a dot at a time and modulating the laser directly at high frequency, much… …
8Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… …
9Carbon dioxide laser — The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed (invented by Kumar Patel of Bell Labs in 1964 [cite journal last = Patel first = C. K. N. authorlink = C. Kumar N. Patel year = 1964 title = Continuous Wave… …
10TEA laser — The CO2 TEA laser was invented in the late 1960s by Dr Jacques Beaulieu working at the Defence Research Establishment, Valcartier, in Quebec, Canada. The development was kept secret until 1970 when brief details were published.C K N Patel,… …
