with these close-in effects either.

Hi Gene,

Nutz, I thought I had mentioned Plasmons some time or other....

Where are the equations that describe this "delta-t" stuff that you keep
bringing up? How long is delta-t? What justification do you have for
saying that the waves start out from some point and then shortly
thereafter decide to cancel? Do they annihilate each other suddenly or
is the interaction gradual from time zero up to delta-t? Do you have any
references for this behavior? I scanned the Melles Griot tutorial info
and the FSU website, but I couldn't find anything about delta-t.

Except for the conceit of "delta-t," I bet you already can answer the
other questions with positive examples (and that you are well aware
that the Melles Griot material is -um- light years behind in these
topics).
