rod laser or Photoflash as the physical dimensions are about right for 
that application (rod laser uses xenon discharge tube as a optical 
excitation source)

Both are charged slowly from a HV DC source

I use a pair decades ago in a voltage doubling circuit.  The voltage was 4 KV, divided among the two caps.  The amp is still running flawlessly.
