The beam can be aimed in many directions, including towards vehicles moving. However, a powerful laser may radiate its beam so wide that it's impossible to be observed from a vehicle. In these instances, a higher-powered laser can be employed.<br><br>The power of the laser beam from a pointer varies. A 200mW green laser can be observed from one mile. A 1000mW red laser can be seen from 10 miles away. Certain lasers have a shorter distance. According to ScienceDaily.com the world's largest laser is 270 kilometers long. It is important to note that a projectile or laser within space will continue to radiate light till it hits something.

It's possible to use a 50mW laser and it'll be able to work as far as it's supposed to. A laser pointer with 5mW can be dangerous and can be distracting.<br><br>Laser pointers are intended to operate at a low power level. If you've got an optical source that has just a few thousand milliwatts in power and you are able to see it for up to a mile. In the case of an airplane, it may be impossible to observe the laser pointer , unless it's directed at your eyes.
