Taking into account the stochastic excitation of the atoms (as quantum structures), we can suggest an absolutely new conception of a wide spectrum of processes in a femtosecond laser produced plasma. The electromagnetic fields being achieved with the modern laser technique exceed intraatomic fields by several orders. This fundamentally changes the physics of their interaction with the atomic structures. The atom effectively transforms the energy of radiation falling on it into fluxes on the nucleus. Quantum systems spin interaction with vector potential field being to play the essential role.
