lol i just said that!
Tthe concept of decanning is a bit scary to me. How do you remove the metal can, which is made of the very hard metal alloy Kovar, if I recall, without damaging the laser die or the fine wires soldered to it? Just for fun, i tried it on an old 5.6 IR diode from a CD player and successfully destroyed everything in it even though I tried to be very careful and peeling the metal away from the core...
I think people who successfully de-can a diode are either wizards, ninjas or extremely small people with equally small tools.

my understanding is it's not good to remove the can because contamination will shorten diode life.
Peace All Pyro... :eg:
Flaminpyro is correct.
The higher energy 405nm beam will decompose materials in the path and deposit them on the laser output mirror.
A decanned BR diode will work fine, but is more subject to foreign materials between the diode and the lens.
