Ummm...you are going to damage your eyes with that thing. ANy laser strong enough to burn anything will damage your eyes if you shine it on a dull, unshiny surface and look at the surface. You won't need to shiny directly into your eyes, or even a shiny surface.
Did I also mention it's illegal to have an uncertified, class IV laser? In fact, I think any unenclosed Class IV (ie. burning) laser is illegal...military R&D excluded.
Think now...planes pilots, car drivers, houses, trees, passerbyers...etc.
