Where can I find an online tutorial on laser safety at powers up to 10W? I know some of the more powerfull lasers can cause burns and damage to the eyes, can they burn skin? Paper? Tin foil? Should I have some sort of absorbive load at the end of the beam when I'm testing? A brick? A hunk of charcoal? Any ideas?
