Below is an essay on "Laser" from Anti Essays, your source for research papers, essays, and term paper examples.

The word "laser" is actually an acronym meaning "light amplification by stimulated emission of radiation." Lasers produce light through electromagnetic-radiation induced emissions. Laser lights can be manipulated to form high-concentration beams or wide-spread beams through the use of lenses and mirrors.
Gas Lasers
A specific type of laser is the gas laser. There are many types of gas lasers, as each one uses a specific type of gas to create the laser emission. For example, a helium-neon laser uses HeNe to produce varied wavelengths. Because of the flexibility of this laser light, it can be created through a low budget, making it especially useful in education institutions and other organizations with limited funding.
Chemical Lasers
Another type of laser is a chemical laser, which is created through artificially induced chemical reactions. These chemical lasers are capable of high energy outputs and deliver consistent emissions, making them very useful for machines and equipment that require continuous operation.
Excimer Lasers
Excimer lasers also call on the power of chemical reactions. Although not in every single case, they usually tend to create ultraviolet light and are used in semiconductor photolithography and in LASIK eye surgery. LASIK eye surgery has become a commonplace procedure, allowing patients to receive treatment and return home the same day.
Solid State Lasers
Solid-state lasers are among the most useful lasers that exist today, finding applications in a number of different arenas. This laser technology is used on a daily basis, including materials processing, such as welding and cutting. Solid-state lasers are also used in semiconductor fabrication, graphic arts and medical and surgical operations and procedures.
Laser lights are also used as simple, harmless laser pointers for school and office presentations. These handy devices help people point to exact locations on slides, helping them deliver smooth-flowing, precise...
