A laser is an electronic-optical device that produces coherent radiation. The term "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.[1][2] A typical laser emits light in a narrow, low-divergence beam and with a well-defined wavelength (i.e., monochromatic, corresponding to a particular colour if the laser is operating in the visible spectrum). This is in contrast to a light source such as the incandescent light bulb, which emits into a large solid angle and over a wide spectrum of wavelength. |
