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.
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.
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.
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.
Lasers are increasingly being used in dentistry as technology advances. Lasers can be used for a variety of dental procedures, including teeth whitening, cavity detection, and even tooth removal.
