Fred - interesting observation - even without a plasma...
(and even for those like myself who are on a brain transplant
waiting list ;-)
Stimulated Brillouin Scattering is possibly active in the context
of the Letts/Cravens and other experiments recently mentioned
where lasers are used. However, one suspects that the effect would
have been much greater had terahertz lasers been available to them
and at signigicantly higher power.
Stimulated Brillouin scattering (SBS) in a plasma is said to be
due to the interaction of an electromagnetic wave and an ion
acoustic wave (Alfren wave). And one must suspect the same thing
is going-on in condensed matter to the degree that the laser light
can penetrate the material (a few microns). Ther penetration depth
for terahertz, for comparison purposes, is many cm and it can be
identical in lamda to the phonon frequency.
A loaded D-matrix is comparable to a large number of subnanometer
"chambers" and laser light will certainly penetrate the surface -
which is hte active area anyway, but a terahertz coherent light
source (can be a diode and not a laser) would seem to be ideal.
Too bad they are not commonly available.
SBS is identified by a characteristic "frequency shift" according
to the literature.
http://tempest.das.ucdavis.edu/mpi/SBS/SBS.html
"Here we report the first observations of SBS in microwave
interaction with plasma, finding not only the frequency downshift
in the reflected wave, but directly measuring the wavelength of
the ion acoustic fluctuation. An interesting feature of these
experiments is that a small chamber reflectivity sets up ion
fluctuations which then serve as an enhanced noise level for the
initiation of the SBS. After an initial fast growth time, we find
the SBS reflectivity growth rate to agree with the classical
calculations."
When I read the part about "downshifting," it occured to me why
the Mills microwave experiment is so effective even thought they
are using a conventional oven power supply at 2.45 GHz which is
higher than the hydrogen resonance at 1.4 and not a "precise"
harmonic. Perhaps the "Evenson cavity" has the effect of
downshifting this to precise hydrogen resonance.
BTW these chambers are nice - if they weren't the price of a good
used car:

For those not on a brain transplant waiting list (for honing their
OFF TOPIC skills)
here is a 140 page pdf thesis that touches on the 1964 Garmire and
Townes experiment
that converted laser/maser light into intense sound waves in
liquids and solids.

Germane to the Chubbs' phonon-phonon-light effects seen in the CF
experiments.

Taking a cue from the Chubb phonon theory plus experiments that
seem to support it, surrounding a UV fluorescent tube with D2O in
a reflective metal cavity might effect CF if the energy density
is sufficient.
Ed Storms has/had one of these (4 watt) in an Eprom 254 nanometer
uv eraser unit that I sent
him several years ago.
The deuteron density in D2O is greater than it is in deuterium-
palladium.
