The beam can be aimed at many different directions, and even towards moving vehicles. However, a laser with a high power can radiate its beam so wide that it's impossible to be seen from vehicles. In such situations it is possible for a more powerful laser to be employed.<br><br>The power of lasers in an object varies. A laser with a power of 200mW can be observed from a mile away. A 1000mW red laser could be visible for ten miles away. Some lasers have a shorter range. According to ScienceDaily.com the world's longest laser spans 270 km. It is important to note that a projectile or "laser" in space will radiate light till it hits something.

They can be too powerful for the distance they cover. It is recommended to store the laser in a closed housing to avoid spills that could happen. And while you're there, make sure to verify the range of the laser. This is a great way to be safe and avoid an unsafe situation!<br><br>There are many different methods of determining the distance a laser pointer can travel. It is estimated that the distance from Earth to Moon will be 238 miles, and it's possible to find one that's powered by 500mW. It's possible to use an flint laser of 50mW and work at least as far as it's supposed to. Utilizing a laser with a power of 5mW can be dangerous and distracting.<br><br>Laser pointers are supposed to function at a low power level. If you've got an optical source that has at a few thousand milliwatts and you are able to see it for as long as a mile. If you're on the air, it could be impossible to observe the laser pointer unless it's pointed at your eyes.
