Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.
The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. [1] [2] 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.
A helium–neon laser or He-Ne laser is a type of gas laser whose high energetic medium gain medium consists of a mixture of ratio (between 5:1 and 20:1) of helium and neon at a total pressure of approximately 1 Torr (133 Pa) inside a small electrical discharge. The best-known and most widely used He-Ne laser operates at a wavelength of 632.8 ...
The LaserDisc ( LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as MCA DiscoVision (also known simply as "DiscoVision") in the United States in 1978. Its diameter typically spans 30 cm (12 in). Unlike most optical-disc standards, LaserDisc is not fully digital, and instead ...
Nd:YAP laser (yttrium aluminium perovskite) 1.0646 μm [7] Flashlamp, laser diode. Surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam) Nd:Cr:YAG laser. 1.064 μm, (1.32 μm) solar radiation. Experimental production of nanopowders.
Argon fluoride laser. The argon fluoride laser (ArF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 193-nanometer wavelength, it is a deep ultraviolet laser, which is commonly used in the production of semiconductor integrated circuits, eye surgery, micromachining, and ...
Milling with a laser is a three dimensional process that requires two lasers, but drastically cuts costs of machining parts. Lasers can be used to change the surface properties of a workpiece. The appliance of laser beam machining varies depending on the industry. In light manufacturing the machine is used to engrave and to drill other metals.
Laser engraving. Laser marked electronic part. Laser engraving is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which in some cases, also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, and more.
