Abstract

The mechanism underlying a new approach to the formation of molecular transitions is suggested and substantiated. It is demonstrated under what conditions a biharmonic wave packet field and a field of elastic optical collisions initiate the transformation of molecules into an ensemble of diamagnetic optically active open molecule-photon systems through the second-order phase transition and how cooperation arises between the polarization and induction energies corresponding to two rotational transitions coupled by the lowest rotational state with J = 0 and then inversionless generation of radiation with large orbital angular momentum Mz >> 10h per photon is self-excited at a forbidden (according to the strict selection rules) rotational magnetic dipole transition.
