Brainiac75 | Bad Beams? | How divergent are lasers? @brainiac75 | Uploaded May 2021 | Updated October 2024, 3 days ago.
Laser beams are amazing to watch since they appear like a string of light. Not like a wash of illumination from other light sources.
But does a laser beam spread out? Does it diverge - getting wider over distance? Let's measure the divergence of my cheapest and most expensive lasers!
