The most frequently asked question by pupils is "How far is a laser-pointer's range?". A blue laser of 1W can easily cover as far as 450 miles and is useful for presentations. The beam can be directed at many different directions, and even towards moving vehicles. However, a powerful laser may extend its beam to the point that it's impossible to be seen from vehicles. In these instances it is possible for a more powerful laser to be employed.

The power of lasers in an object varies. A 200mW best green laser pointer laser can be observed from a mile away. A 1000mW red laser could be visible for ten miles away. Certain lasers have a smaller distance. According to ScienceDaily.com the world's largest laser spans 270 km.
