How far can a laser travel
Web24 apr. 2007 · The light will still be traveling towards you but you may not see it. looking at a laser beam from the side is another matter entirely. a low powered laser beam can only be seen within a few degrees of the source. the higher the power, the greater the number of degrees away from the source you will be able to see it. WebIn contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. This is why light from distant stars can travel through space for billions of light-years and still reach us on earth.

Web1 milliwatt (mW) handheld lasers have a 2,139 to 4,555 square meter wide travel distance. A 1W laser pointer has an even greater range. It’s worth noting though that the higher the power of the laser beams, the greater the divergence. WebA laser beam diverges and will not stay focused forever. With a beam divergence of 1 mRad, the laser will have a beam width of 10 m over 10 km. It means the observer at 10 km away in the middle of the beam can change their height by 5 m and still be able to see the direct laser beam. Lasers are just a form of light.
