Hanna D. C. Fibre Lasers, in Laser Sources and Applications, ed. by Miller A. and Finlayson D.M. (Institute of Physics, Bristol, 1996). <...> Principles of laser radiation on the prepared magnetic dipole transitions V. P. Lopasov Zuev Institute of Atmospheric Optics, SB RAS. 1 Academician Zuev sq., Tomsk, 634021, Russia E-mail: lopas@iao.ru Clarified are the principle and mechanism of generation of laser radiation on the electric dipole transitions of the molecules (atoms). <...> Obtained are principles of self generation of laser radiation on the magnetic dipole nonrigid electronic transition to be prepared in an ensemble of optically active nanoparticles of electron-ion. <...> Presented are estimates, which revealed the advantage of laser on magnetic dipole transitions. <...> PACS: 42.55.-e, 42.50.Nn, 42.55.Tv Keywords: molecular optics, optically active medium, laser, coherence, spiral wave front, the angular orbital momentum. <...>
