Is such?

The laser must be fed into a non-linear medium for the doubling to

Very interesting.
May be it take place. You do not analse the intensity after each doubling..
My question apply to the two sources emitters (oscillatig dipole) in a
lineaar medium.
S*
The presence of a non linear medium is always required for frequency
doubling. The only part of the atmoshere that I know of that meets the
qualification is the ionosphere which contains plasma which could act
as a nonlinear medium. I suppose that if the signal were powerful
enough to produce ionization that a frequency could be doubled..
