I am new to this board, but from what I see, everyone seems to be running the laser diodes in cw mode. Most all the diodes being used in the laser pointers could be run at significantly higher outputs if a pulsed driver was being used.
I did a brief search on a suitable circuit andf found this one. http://www.ee.oulu.fi/~arik/Pulse.pdf
With the exception of the heatsink required, I think this can be built for un der $20 and it could supply 2.5 amps at its low end just by changing some values in the shown schematic. And it can run up to a 100 amps as shown (it shows 5->100 amps in the supplied schematic).
