Abstract

Abstract A plurality of laser beams emitted from lasers are reflected by mirrors to form a bundle of parallel beams or converged by mirrors into a limited narrow space. Lasers and directing mirrors may be arranged on two or more planes to increase the number of beams per bundle. An ultra-high power, ultra-high density pseudo-single laser beam can be generated by use of one or two groups of reflecting mirrors and a focusing mirror for focusing the beams from the reflecting mirrors into one focal point.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 106 words
An apparatus for generating an ultra-high power, ultra-high density pseudo-single laser beam, comprising: a plurality of lasers arranged around a reference axis for generating a laser beam toward the reference axis; a plurality of directing mirrors arranged around the reference axis in one plane perpendicular to said reference axis for directing said laser beams from said lasers at a predetermined angle; a plurality of reflecting mirrors arranged around the reference axis in another plane for reflecting said laser beams from said respective directing mirrors at another predetermined angle; and a central focusing mirror for focusing the laser beams from said reflecting mirrors into one focal point.
Claim 2
Independent Claim 106 words
