>>12726300>These experiments also conceptually demon-strate the classical limit of an important quantum effect,
i.e. the particle creation by the mixing of positive and
negative frequencies [12]. This implies that the process
could, if sufficiently optimised, generate a squeezed
vacuum state that couples wavelengths around ?RR to
wavelengths at the negative RR peak, ?N. At a classical
level, the mixing of positive and negative frequencies
leads to simultaneous wavelength conversion to the UV
region and amplification (at the UV wavelengths) of
an input seed pulse that co-propagates with the input
pump pulse. These ideas will be developed in future
work.
Interesting. Tooker, can you write up a tutorial for how to turn UV light into Au with this method?
