godmonkey said:what heatsinks were people running with the ~150mw builds? If one would use active cooling couldn't the laser be pushed alot harder?
No one is actually expecting these to run at 150mW with any type of heatsink. Heatsinking is not really so much of a problem here. The AixiZ module itself is a heatsink already. A chunk of alluminum on it would slowly pull the heat out, but that wouldn't really help, since it is still not that much heat. The diode would die from other causes, or if it would die from heat, it would be internal heat, which no heatsink can pull away fast enough.
Heatsinks do not allow the use of higher currents only longer run time. Active cooling with a peltier might help a bit, but you still can not expect 150mW realistically.
In fact, i would not suggest going over 90mA if you want good diode life. Look at how the power output graph changes just after 90mA. The power starts increasing more slowly, and the heat starts increasing more.
If you wanted to get an obscenelly high power like 150mW you would probably have to kill 6-10 diodes, to find one capable of it, and even then you wouldn't really know how long it would live, no matter how good you would cool it.
