Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align. First developed in the 1960s to amplify microwaves, modern lasers technology can ramp up light rays in just about any part of the electromagnetic spectrum, with the exception of gamma waves. Inside a laser, atoms in a special material are first “pumped” with energy, typically from an electrical current or a bright flash of light. This pushes electrons in those atoms into a higher energy state, like pulling back a spring. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. All light sources convert input energy into light. In the case of the laser, the input, or pump, energy can take many forms, the two most common being optical and electrical. For optical pumping, the energy source may be a lamp or, more commonly, another laser. A laser is a device that generates a narrow, focused beam of light. Unlike ordinary light, which contains many colors and spreads in all directions, laser light is mostly one color, with coherent waves that move together in step. A laser is not just light; it is light disciplined, sharpened, and focused into a beam so pure and precise that it can travel across the Moon, cut through steel, perform delicate eye surgery, or carry billions of internet messages in a single second. Lasers are amazing light beams powerful enough to zoom miles into the sky or cut through lumps of metal. Although they seem pretty recent inventions, they've actually been with us over half a century: the theory was figured out in 1958; the first practical laser was built in 1960.
