New Research Suggests that a Neutrino Laser is Impossible
In a review paper by [Ana Maria Rey] et al. these two papers are investigated in more detail. The problem lies in taking the leap from photons with a BEC and applying this to a BEC of radioisotopes. Whereas photons are relatively slow and low-energy at a mere 1 eV, a neutrino is extremely fast and at 1+ MeV correspondingly has a much greater kinetic effect on the particle that emitted it.

New Research Suggests That A Neutrino Laser Is Impossible No comments by: Maya Posch September 21, 2026 Title: Copy Short Link: Copy As cool as it would have been to wield lasers that produce a beam of neutrinos, recently two papers were published by MIT researchers that seem to dampen the likelihood of such lasers being at all possible. In a review paper by [Ana Maria Rey] et al. these two papers are investigated in more detail. Although the concept behind a neutrino laser is rather simple, using the same superradiance effect involving a Bose-Einstein condensate (BEC) that allows for stimulation by photons to result in a synchronized direction of emitted photons, the idea of using a BEC of radioisotopes that naturally emit neutrinos in this fashion has now been effectively shot down.
