YAG Lasers
Yttrium aluminum garnet lasers, also referred to as "YAG lasers," are solid state lasers that use neodymium-doped YAG crystals as the lasing medium. YAG lasers are available in constant and pulsing configurations and are generally used for such processes as laser marking, cutting, and welding. Other applications are found in ophthalmology, cosmetic medicine, manufacturing, and fluid dynamics.
Lasers are demarcated according to the lasing media that they employ. Solid-state lasers like YAG lasers have lasing material distributed in a solid state. Using a flashlamp or laser diodes, YAG lasers are pumped optically. They are frequently used in multiple industries.
Exposure to YAG lasers can cause severe damage. Built in engineering controls are required in laser systems to provide safety. All lasers, no matter what their power, must have an enclosure around them that limits access to the laser beam or radiation. Other safety controls that may be instituted include access restriction to the lasing area, eye protection, area controls, barriers, shrouds, education, and training.
