The beam is able to be directed at many different directions, and even towards vehicles moving. However, a laser with a high power can radiate its beam so wide that it would be unable to be observed from a vehicle. In these instances the use of a laser with a higher power can be employed.<br><br>The power of the laser beam from an object varies. A green laser of 200mW could be seen from over a mile away. A 1000mW red laser can be visible from ten miles away. Certain lasers have a smaller range. According to ScienceDaily.com, the world's longest laser spans 270 km. It's important to know that a projectile, also known as a "laser" in space will continue to radiate light till it strikes something.

They can be too powerful in relation to the distance they reach. It is recommended to store them in a sealed housing to avoid spills that could happen.

Using a 5mW laser pointer can be dangerous and can be distracting.<br><br>Laser pointers are intended to operate at a lower power level. If you have a laser that is just a few thousand milliwatts in power that you can see for as long as one mile.
