  Molecular Dynamics and Sarastro before it, have always computer controlled
  laser power.  For most users the laser spends most of its time in "stand-by"
  mode waiting for the investigator to find something to scan or get a cup of
  coffee.  Perhaps this is why we don't see a significant difference in the
  lifetimes of Ar or Ar/Kr lasers (thousands of hours!)

  happy scanning,
