Query: Sub-frequency search at a laser as a signal of dark matter sector
  particles   We introduce a new method to search for the dark matter sector particles
using laser light. Some dark matter particles may have a small mixing or
interaction with a photon. High-power lasers provide substantial test grounds
for these hypothetical light particles of exploding interests in particle
physics. We show that any light source can also emit a sub-frequency light as a
new physics signal. Searching for this sub-frequency light at a laser can be a
simple and effective way to investigate the new light particles, even in
tabletop optics experiments.
