The PGL-III has a 1.2W 808nm C-mount pump diode. I just noticed that there's a 4W 808nm C-mount diode on eBay. Anyone dare?

Make the swap and modify the driver board (or replace it with a different one) to supply 6A of current, and you would probably have the world's most powerful portable laser. Perhaps over 1W of 532nm. The PGL-III units that have the 0-9 adjustable power output and the driver board in the end cap have nothing but a matrix of resistors controlling the current that goes to the pump. It should be possible to supply 6A with the right (large) resistor.
