Scientific American published articles on making your own HeNe LASER
back in the late 60's/ early 70's that among other things detailed
making your own getters to purge the LASER tube. (I remember it
because my buddy and I tried to make a LASER as a high-school
science project. We got a nice tour from the folks at MIT out of it.
Sadly, our mirror mounts never worked out.)

you think. You probably don't care what my empolyer thinks. Thus is
life a circle.
