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.
405nm lasers are a type of near ultraviolet (UV) laser that can be used to excite fluorescence in a wide range of molecules. When this type of laser light is shone on certain materials, they will emit light at a different wavelength in a process known as fluorescence.
A diode laser is a device that emits light through the process of stimulated emission. The word “diode” comes from the Greek prefix “dio,” meaning two, and refers to the fact that there are two electrodes in a diode laser: a cathode and an anode.
