Device that emits light through amplification
http://www.pgsciencecity.org/assets/website/pdf/laser.pdf WebA laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. 2. In lasers, the photons have the same wavelength, which makes them coherent and monochromatic. Light, on the other hand, has multiple wavelengths, which results in a spectrum of different colours.
