Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser to fuse together small particles of plastic, metal, or ceramic powder into a three-dimensional (3D) object.
Laser safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, injury to the eyes or skin, or damage to property.
Laser diodes are semiconductor devices that emit light when an electric current is passed through them. The two main types of laser diodes are single mode and multimode.
A dye laser is a laser that uses an organic dye as its gain medium. The dye is usually dissolved in a solvent, such as ethanol, and is pumped by a laser beam to produce laser action. The wavelength of the laser light is determined by the properties of the dye, and can be tuned by changing the dye.
Lasers have been used in industrial settings for decades, but their use has been largely limited to cutting and welding applications. However, recent advances in laser technology are beginning to open up new possibilities for using lasers in a wide range of material processing applications.
Argon-ion lasers are a type of gas laser that uses an argon plasma to produce light. The first argon-ion laser was built in 1964 by William Bridges at the Hughes Research Laboratories.
A helium–neon laser is a gas laser using helium and neon as the active medium. The output of a helium–neon laser is a coherent beam of visible light with a wavelength of 632.8 nm, which is in the red region of the visible spectrum.
Laser therapy is a medical treatment that uses focused light to treat various conditions and injuries. The laser light is applied directly to the skin, which allows it to penetrate deep into the tissue. This type of therapy has been shown to be effective in treating a variety of conditions, including pain relief, wound healing, and reducing inflammation.
Laser pointers are becoming an increasingly popular hobby for people of all ages.
CO2 lasers are the most commonly used type of laser in industry and are used in a variety of applications including cutting, welding, and engraving.
