Abstract
Abstract An electric generator comprising a compressed and excited gas supply flowing at high speed in an optical resonating cavity to form a laser, the gas then passing between two electrodes. A magnetic field is applied between these two electrodes, and the laser beam is focused in the interelectrode space to increase the electronic density of the gas. A high potential is thus produced between the electrodes.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
159 words
Electric generator characterized in that it comprises: a. a source of compressed and energized gas; b. a duct means arranged at the output of said source for producing a high speed gaseous flow to be obtained by expansion of said compressed and energized gas; c. an optical resonating cavity means arranged at the output of said duct means such thAt the gaseous flow passing through said cavity produces a laser beam; d. at least two electrode means defining an inter-electrode space for the gaseous flow after passing through said cavity, wherein said gas passes through said inter-electrode space; e. means for applying a magnetic field to the inter-electrode space; and f. means for focusing, in the inter-electrode space, said laser beam produced in said optical cavity, whereby a high potential is obtained between said electrodes due to the increased electronic density in said gas caused by the focusing of the laser beam, and the application of the magnetic field.
