Mark, I agree with your observation -

If it's real, it should be much easier to explore the experimental parameter space than with other approaches, and less expensive. Also, broadband incoherent e-m sources might be better at finding resonances and also provide higher amplitudes sporadically. Swept frequency sources and signals like Energetics' Superwave which provides superoscillation amplitudes might be worth trying. - Lou Pagnucco Mark Jurich wrote: > I don't find the use of an incoherent light source that surprising. > The Coherence Length of a Light Source is inversely proportional to its > Bandwidth.
