Wondering what you use to safely stop a beam? I'm getting a 2W PL-E mini from jetlasers, and am assuming it's not good to just have it pointed at a wall or something.
Beefy black anodized heatsinks work well too. The fins act as a bit of a baffle, helping contain any specular reflections.
Hello,
what do you want?. Do you like to see the focused beam on a target or do you want to absorb all the light on the target? In this case I would suggest to use a black box with black velvet inside and a hole at the target side.
best regards
Edgar
Lol farther than the distance to any wall in your house.If I have it set up on my desk for burning, I just want to have the beam terminate on something besides the wall. At what distance will a 2W 445 laser no longer burn things?

Another solution would be to use a short negative focal length lens that will diverge the beam
Not 100% sure but I think what Steve had in mind was to focus the laser to as fine a point as possible for burning at a range of a few inches. Focused that way the beam would then diverge rapidly away from the 'work' area.I don't think it's a good idea to use any kind of glass beam stop not even a lens unless the whole system is bolted down, if it's not bolted down then it's a reflection hazard.
