A laser beam is subjected to repeated reflection by a plurality of concave mirrors disposed in a confronting arrangement. Reflecting paths are centralized to form an interactive region of a high photon density. An interaction target such as gas, liquid, a solid body, plasma, a particle beam and an electron beam is introduced into the interactive region. Interaction with the laser beam causes optical interactions such as optical excitement, optical ionization, optical dissociation, optical synthesis, optical generation and optical analysis.
