On the possibility of laser-assisted production and detection of low-energy neutrino beams

The possible production and detection of collimated beams of low-energy sub-keV neutrinos with the assistance of lasers is examined. For a neodymium laser, the relative probability that recoiling co- or counter-propagating neutrino-antineutrino pairs are created in stimulated emission events instead of photons is calculated to be about 10-7. The effect generates a coherent monochromatic neutrino beam that overlaps the internal standing-wave photon beam, exiting at both ends of the laser. To detect such (anti)neutrino beams without the help of absorption, one can exploit (anti)neutrino-stimulated deexcitations of lasing levels in a second laser aligned with the first, whose lasable transitions are resonant with the undulation frequency of the (anti)neutrinos.
