Abstract
Abstract A laser head is constructed with a three-plate capacitor wrapped around the head. The capacitor plates are triangulated to assist in beam formation. The power supply is a resonant charge circuit, with a switch arrangement for regulating the extent of charge accumulated before the laser is fired, and the firing is regulated by another switch. The entire system is compact and constructed to utilize laser heads of different diameters, without changing the power supply or other components of the system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A laser head comprising a cylindrical member and a capacitor assembly concentric with said cylindrical member, characterized in that the capacitor assembly comprises at least three metallic foil members, with the edge portions of two of the metallic members extending through the cylindrical member to form electrodes, a plurality of insulating sheets interspersed between the metallic foil members to provide insulation in the capacitor assembly, and further characterized in that each of said metallic foil members is substantially triangular, to assist in beam formation in the laser.
Claim 2
Dependent Claim
87 words
A laser head comprising a cylindrical member and a capacitor assembly concentric with said cylindrical member, characterized in that the capacitor assembly comprises at least three metallic foil members, with the edge portions of two of the metallic members extending through the cylindrical member to form electrodes, a plurality of insulating sheets interspersed between the metallic foil members to provide insulation in the capacitor assembly, and further characterized in that each of said metallic foil members is substantially triangular, to assist in beam formation in the laser.
Claim 3
Dependent Claim
65 words
A laser head as claimed in claim 1, and further characterized in that the edge portions of the metallic foil members which extend into the cylindrical member are each turned at right angles and follow the curvature of the cylindrical member for a short distance, thus providing diffusion electrodes in the interior of the laser head, providing a wider beam than would otherwise be produced.
Claim 4
Dependent Claim
75 words
A laser head comprising a cylindrical member and a capacitor assembly concentric with said cylindrical member, characterized in that the capacitor assembly comprises at least three metallic foil members, each of said metallic foil members being substantially triangular, with the edge portions of two of the metallic members extending through the cylindrical member to form electrodes, and a plurality of insulating sheets interspersed between the metallic foil members to provide insulation in the capacitor assembly.
Claim 5
Dependent Claim
75 words
A laser head comprising a cylindrical member and a capacitor assembly concentric with said cylindrical member, characterized in that the capacitor assembly comprises at least three metallic foil members, each of said metallic foil members being substantially triangular, with the edge portions of two of the metallic members extending through the cylindrical member to form electrodes, and a plurality of insulating sheets interspersed between the metallic foil members to provide insulation in the capacitor assembly.
Claim 6
Dependent Claim
65 words
A laser head as claimed in claim 3, and further characterized in that the edge portions of the metallic foil members which extend into the cylindrical member are each turned at right angles and follow the curvature of the cylindrical member for a short distance, thus defining diffusion electrodes in the interior of the laser head, providing a wider beam than would otherwise be produced.
Claim 7
Dependent Claim
156 words
A laser head comprising a pair of semi-cylinders, characterized by a first triangular metallic foil member having an edge portion affixed to one of the semi-cylinders along an edge and the adjacent interior portion thereof, a second triangular metallic foil member having an edge portion affixed to the other of said semi-cylinders along an edge and the adjacent interior portion thereof, means for joining said first and second semi-cylinders to form a substantially cylindrical unit with the metallic foil members extending outwardly, a third triangular metallic foil member having an edge portion affixed to the substantially cylindrical member, and a plurality of insulating sheets interspersed between the metallic foil members in the appropriate positions to provide electrical insulation between the foil members when the cylindrical member is rotated to wind the metallic foil members and the insulating sheets in an annular configuration about the cylindrical member to provide a capacitor assembly concentric with the cylindrical unit.
