Abstract
Abstract Glass compatible metal matrices are mounted in a glass forming boat and slugs of glass are applied to each. Heat is provided such that openings in the matrix are glassed, whereupon the entire sheet may be ground, polished, or otherwise processed as desired. Alternatively, open ended metallic portions may be utilized to control the amount of sag to which heated glass is subjected, thereby providing glass components of a desired radius of curvature. When metal framed optical components are secured in lasers by weldment, controlled crimping and deflection of the metallic laser jacket portion is utilized for precise alignment of the instrument.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A method of manufacturing laser apparatus, comprising: a. fabricating a laser tube enclosure having metallic portions at least at the prospective location of optical components; b. completing the fabrication of said laser to integral structural completeness; c. energizing said laser; and d. deflecting said enclosure by applying pressure to metallic portions of said enclosure, thereby optimally aligning said optical elements, characterized in that said deflecting step comprises at least once i. mounting said metallic portion on a metal processing vise having a movable top portion and an opposing fixed base member, ii. applying pressure to said top portion to cause a crimp to be formed at the point of contact of said top portion against said metallic portion, correspondingly deflecting an optical component relative to the axis of said laser, while monitoring the coherent light output of said tube.
Claim 2
Independent Claim
139 words

Claim 3
Dependent Claim
39 words
A method as described in claim 1 wherein said completing step includes: fabricating optical components of metallic periphery and glass center portions; and securing said components by weldment of said metallic periphery to said metallic portions of said enclosure.
Claim 4
Dependent Claim
25 words
A method as described in claim 1 wherein said deflecting step is repeated a plurality of times at different predetermined positions along said metallic portion.
Claim 5
Dependent Claim
92 words
A method as described in claim 3 wherein said fabricating step includes providing a laser tube enclosure having an elongated metallic neck portion at at least one end, wherein said completing step includes welding a brewster angle window within said neck and an end mirror at the terminus of said neck, and wherein said deflecting step is performed at least twice by consecutively locating said vise on the side of said brewster window opposite said mirror, and then locating said vise at at least one point intermediate said window and said mirror.
Claim 6
Independent Claim
145 words
A method of manufacturing laser apparatus comprising: fabricating a laser tube enclosure having metallic portions at least at the prospective location of optical components; completing the fabrication of said laser to integral structural completeness; energizing said laser; and deflecting said enclosure by applying pressure to the metallic portions of said enclosure, thereby optimally aligning said optical components; wherein said completing step includes fabricating optical components of metallic periphery and glass center portions; securing said components by weldment of said metallic periphery to said metallic portions of said enclosure; and wherein said fabricating step comprises providing a plurality of metallic annular elements; placing said elements in a mold having cavities around at least part of each of said annular elements; providing glass slugs in each of said cavities; forming glassed annular portions of said elements by melting and cooling said slugs; and optically finishing said glass.
