All crazyness aside, i do wonder how well these things would perform if cooled to extremes. Dunking one in liquid N2 just to see what happens would be fun, though i think it might just crack due to rapid thermal compression.
I think i'll have a go a finding that knee point once i get some proper cooling for the module. The little heatsink star that i have around it now isnt all that effective.
I saw an interesting piece of alu intended to mount a hinge on a wall (or pole) in the dyi shop. I hope they have one where i can fit the module in and mount it on a larger heatsink (think CPU sized).
As for monitoring voltage: I've taken some measurements at currents between 40 an 160 mA, the relation seems similar to that of LEDs so far. Guess i'll find a cheap extra meter somewhere so i can watch both simulatnously though i don't expect any exciting results.
If you graph the LD current vs Po, you will see a knee (leveling curve) in the graph showing that the diode is at it's limit. Back-off !!!
