Laser 10
Laser 10 : Radiation and Radiological Disasters. Light Amplification by Stimulated Emission of Radiation. Light waves are massed into a very narrow band of wavelengths and sent in a fixed direction giving light as much as a million times brighter and a million times purer than that produced in any normal way. A laser beam can be used to detect a fire in large enclosed spaces owing to the bending of the beam as it passes through heated air
