Raman discovered that some substances can rework one frequency into
many (also in higher).
May be that a cotton screan also rework.


This is a subject I have considerable experience in. My group at Eastman
developed a process Raman spectrometer that used communications grade
fibers to transmit both the excitation wavelength and the anti-Stokes
Raman scattered light. Chalcogenide fibers, at around $1K per foot,
would be needed to transmit the IR wavelengths needed for the analysis we
were doing. The communication grade fibers cost less than one foot of
the expensive fibers for the entire several hundred feet needed to
separate the analyzer from the chemical process. Our patents were
eventually licensed to the Rosemount division of Emerson Electric.

Raman spectroscopy is based on the _non-linear_ (inelastic) scattering of
photons. It is quite weak; more than 100 million photons are reflected
by the linear (elastic) Rayleigh scattering for every photon reflected by
Raman scattering.

I am convinced now that Szczepan Bialek is nothing more than an offensive
troll. It is best to ignore him as the physics newsgroups seem to have
done. May he bask in his own stupidity! Or perhaps he and Art and the
gays and the gay bashers could form their own "alt.troll" newsgroup.
