Do you mean that you want to shine the laser into a beam trap, thus prevent refelctions/scatter?

Yes, especially for indoor operations, something that is placed at the end of the beam to avoid reflections.

I have made, and have seen others as well, a beam trap using a housing containing a bunch of razor blades stacked with the sharp end facing out. It seem to work quite well.

Not sure if this is what you are wanting though.

I wanted to ask if any of you use some material suitable for blocking unwanted scattered radiation from high power laser (for example CO2 or near infrared, 808nm of differente watts). I found some "beam traps" (for example at thorlabs. c o m) but they are expensive and often not availables for international shipments.
Is it possible to find more cheap material which can perform similar functions?

Thanks ;)
