It used to be that Rb's would fail lock because the bulb dimmed from Rb
absorption into the glass, but I think they got that fixed with a teflon
coating.

Thes days most of them ultimately fail from the high operating temperature,
through a variety of mechanisms.

For the CSAC, my bet would be that the laser is the limiting factor.
