Looked at the mode matching of the high power oscillator beam into the pre-modecleaner
situated in the diagnostic breadboard (DBB).  Moved ML2 closer to the pre-modecleaner
and things did not appear to change much.

Keita told me that an interlock prevents operation of the DBB, which I will look into
tomorrow.  It might be that I left something disconnected - although I don't think I
did.
