Conceptual model of a magnetomultipole laser A radically new approach to self-organization in a system collective of fields + molecular gas of an ensemble of optically active electron-ion nanoparticles on a prepared magnetomultipole transition is substantiated. Laser generation is self-excited in the nanoparticle ensemble at the magnetomultipole transition frequency. This radiation has a high-order coherence, σ-polarized vertex field, and large orbital angular momentum.
