looking to limit the range of a laser

Solution
The reason they use lasers for surveying is the ability to travel a long way in a straight line.
It will lose intensity as it passes through the air, but that's about it.
The higher the intensity, the further it will go, so using a less powerful laser may be what you want.

Solution
light never stops, it keeps going on forever, until it enters a black hole, or reaches some unknown part of the universe. whether you have the equipment/technology/good eye to see the light is a different story.

what does this have to do with graphics and displays?
 


When light reflects off a particle, some energy is converted into heat or some other form of energy. The intensity of light is reduced as it travels through the atmosphere, as well being sent in many different directions.
