HeNes can't be cranked up to any meaningful degree - as current increases, power peaks and then drops off - I think Sam's Faq has an explanation of the physics behind this. Small diodes are also not very amenable to high pulse powers as the internal mirror structures get optically damaged pretty easily. A 5mw IR diode is not really much use for anything interesting.

Unfortunately I have no data for the tube...
Looks to me like an old seimens lgr 7631a, I have one, and they're good little lasers, nearly impossible to destroy. Usually around 2-3mw at 632.8nm.
A 5mw IR diode laser could be some fun if you could find a sensor for it. Wireless stuff, and alarms are a common project. If your looking to burn, snag one of those SSY-1's off fleabay, and an extra flash tube or two.

The easiest quick and dirty way to drive HeNe tubes like that is with a Flyback. It might not be very good for tube life, but it works reasonably well.

What to do with a 5mW IR laser?
