[QUOTE="dooberGN, post: 9779330, member: 43761"] Here's a website to explain that. [url=http://spaceplace.nasa.gov/en/kids/laser/index.shtml]The Space Place :: What is a laser?[/url] And this What is a laser? A laser* is a unique kind of light, more intense and concentrated than anything in nature. Laser light differs from white light (such as sunlight, the light we use in lamps or flashlights) in several ways. Light from most sources spreads out as it travels so that much less of it hits a given area as it moves farther from its source. Traveling as a tight, unbroken beam, the laser light does not disperse as much as it moves away from its origin. Also, while white light is a mix of colored light waves, laser light is monochromatic, having a single wavelength which corresponds to one specific color. Identical wavelengths travel parallel to one another for reinforcement, creating a strong beam that can be focused down to less than 0.001 inch in diameter.
