If you turn the pot screw up, you very likely will burn the diode out. If it was sold as a 20 mW unit, with the driver and diode already together, the diode isn't rated for more than that. Do so at your own risk and expense!

There are some similarly great answers to this question in the same thread laserdat started (In the general forum).
