I have had to get a Spectra Physics argon re-tubed for one of our
confocals. It worked well and the re-tubing charge was about half the cost
of a new argon laser. ($5k retubing fee vs. $9.5k for a new argon).
I suspect HeNe lasers will be a similar cost, although you can get red
diode lasers at 635nm for fairly cheap at this point. Some even come in a
tube package that is basically a drop-in replacement for the HeNe. I'd
suggest price checking the cost of a decent 635 diode laser vs retubing
your HeNe, especially since 5mW is relatively low power and diodes are
cheap at these ranges.
Here's an example of a 4mW one in the tube format, although I always
suggest you shop around, but at least it gives you a ballpark value for
price to compare against repair of the HeNe.
