Laser light has several properties that make it different from regular light. First, it is often collimated, which means it travels in a narrow beam for long distances, rather than going off in many directions as regular light does. Laser light is also coherent, which means that the light waves stay synchronized over long distances. It is also monochromatic, that is, of one color.
Some laser beams are invisible, producing light in the infrared or ultraviolet wavelengths.
A laser can produce a short burst of light or a continuous beam. Because it can be focused narrowly, laser light can be much more intense than regular light, especially in bursts. Lasers range in power from a few microwatts to several billion watts in short bursts. Although the completion of this form is not required, it is highly recommended. Also, completion of this form will ensure that companies using lasers will be apprised of any pending State regulations and can therefore, provide comments in a timely manner.
