Laser Pointer

Is it possible to make a green laser pointer 50 MW high?
I have about a 50mW green laser pointer, his forte, but I want to see if I can concentrate the beam enough to make a laser engraving. Suggestions?
The problem is that even if you concentrated to 50 MW in one place identify and keep it on the paper say it is likely that the paper would conduct the small amount of heat away before the temp got high enough to char and flames. You can try with a very good goal, well cleaned, fixed in a holder that is adjustable from a laser mounted and paper. And there are losses heat in the lens. Burning with a laser tends to start about 3 watts if I remember.
