Subfrequency 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 may have small mixing or interaction with photon. High-power lasers provide substantial test grounds these hypothetical light of exploding interests in particle physics. show that any source can also emit subfrequency as physics signal. Searching this at be simple and effective way investigate particles, even tabletop optics experiments.
