Hello, everyone!
I am new to lasers and recently started to build my DVD-Burner laser. So here is the question: How do you stop laser beam of high power (yeah, it's high for me laser? I understand, it must be matte material but what color? White would reflect too much light and black would absorb much heat, aren't they? Please, help. Thank you.
P.S. Cheap/easy obtainable is plus, I don't need something like black body with liquid helium cooling for now
