Abstract
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.
Claims17
An optical interaction device comprising:
- first and second mirror sets which are arranged in a confronting orientation so as to form an optical interactive region with centralized laser beams, each set including a plurality of concave mirrors oriented in annular arrangement around a common axis,
- means for generating laser beams for repeated reflection between said mirror sets,
- laser beam guide means for introducing said laser beams into said interactive region and for outputting therefrom after prescribed number of reciprocal reflections between said first and second mirror sets, and
- means for introducing an interaction target into said interactive region
- each said concave mirror in said first mirror set is oriented in an arrangement such that an incident laser beam is reflected towards a corresponding concave mirror in said second mirror set,
- each said concave mirror in said second mirror set is oriented in an arrangement such that an incident beam from a corresponding concave mirror in said first mirror set is reflected towards a concave mirror adjacent to said corresponding concave mirror, thereby sequentially shifting reflected beams in a circumferential direction of said mirror sets,
- a laser beam reflected by one of each concave mirror of said first mirror set and said second mirror set is in a converged mode whereas a laser beam reflected by the other of each concave mirror of said first mirror set and said second mirror set is in a parallel mode,
- said concave mirrors are oriented so that either of said converged mode laser beam and parallel mode laser beam pass a prescribed position on said common axis, and
- an optical interactive region is formed through centralization of laser beams reflected towards said prescribed position on said common axis.
