LASER Full Form
Full form of LASER is Light Amplification by Stimulated Emission of Radiation, which causes specific atoms or molecules to emit light with a particular wavelength. A small amount of UV light, visible or infrared light is absorbed by lasers.
Optical disc, barcode scanners, laser printers, DNA sequencing equipment, fiber optics, laser surgery, and skin treatments, cutting and welding materials, manufacturing laser chip (photolithography), and military and law enforcement equipment for marking targets and measuring range and speed all use lasers.
