Well, I think this was about the fragile nature of diode lasers.
Yes, like many other semiconductor devices, they are susceptible
to overcurrent and overvoltage, ie. static discharge. But, it seems
they are no more susceptible to this sort of damage than any other
semiconductor device I use.

A lot of people are bandying about that if you even open the package
and peek inside without thousands of dollars of static protection gear,
the laser will be fried! Clearly not true. Now, some guys would just
hook a couple D cells to it with no current limit, and they'd fry it, of
course. But properly following reasonable design rules seems to make
them work reliably.
