Query: Sensitivity to Dark Energy candidates by searching for four-wave mixing
  of high-intensity lasers in the vacuum   Theoretical challenges to understand Dark Matter and Dark Energy suggest the
existence of low-mass and weakly coupling fields in the universe. The
quasi-parallel photon-photon collision system (QPS) can provide chances to
probe the resonant production of these light dark fields and the induced decay
by the coherent nature of laser fields simultaneously. By focusing
high-intensity lasers with different colors in the vacuum, new colors emerge as
the signature of the interaction. Because four photons in the initial and final
states interplay via the dark field exchange, this process is analogous to
four-wave mixing in quantum optics, where the frequency sum and difference
among the incident three waves generate the fourth wave with a new frequency
via the nonlinear property of crystals. The interaction rate of the four-wave
mixing process has the cubic dependence on the intensity of each wave.
Therefore, if high-intensity laser fields are given, the sensitivity to the
weakly coupling of dark fields to photons rapidly increases over the wide mass
range below sub-eV. Based on the experimentally measurable photon energies and
the linear polarization states, we formulate the relation between the
accessible mass-coupling domains and the high-intensity laser parameters, where
the effects of the finite spectrum width of pulse lasers are taken into
account. The expected sensitivity suggests that we have a potential to explore
interactions at the Super-Planckian coupling strength in the sub-eV mass range,
if the cutting-edge laser technologies are properly combined.
