Here is my Laser, Can I mod it?

*Pics* Here is My Laser, Can I mod it?

Here is a laser i purchased over year or 2 ago, i originally purchased it for my airsoft guns, but since then, its just been entertainment.

It is supposed to be rated at 50mW, which i have no way of proving or disproving, but i want to either mod this one, or just buy a second one for burning. This one has a removable head piece, or cover, so im wondering if i'm able to purchase an attachment i can use to focus it? And perhaps this one would be able to burn things?

Here is some pics of the Laser.

Im actually looking to buy a new laser, 2nd laser, that is able to burn things. So i guess i dont have a need to modify this one.
