No matter how many number of times you multiply 1 by 1, you still get 1!
How you got from x1 to x2 to x3 to x4 to x5 to x6 to x7 to x8 to x9 is beyond me...
don't mess with the optics - see if you can remove the board from the diode/optics and hook it up to a circuit like the one Daedal made. You may end up with an even higher powered laser...
