In this document, we'll explain how laser light is produced, why it's so useful, and some of its most common applications.
Laser light has several properties that, together, make lasers useful.
Laser light, on the other hand, is generally monochromatic, meaning that it contains one specific wavelength of light. Lasers can, and do, produce more than one color, but these colors are discrete individual wavelengths of light, as opposed to the broad spectrum of sunlight or fluorescent light. Light from a lightbulb, for instance, has wavelengths that are not nearly as organized, with most photons' waves travelling chaotically and interfering with one another. It's the coherent, organized property of laser light that makes it capable of delivering a high amount of energy in a small beam. In the case of visible lasers, this makes the laser beam very bright and intense.
