Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A gas laser comprising: a. envelope means for enclosing the gaseous medium; b. means for exciting said gaseous laser medium to provide energy levels therein required for laser action; c. a pair of optical resonator mirrors; and d. a mirror support and alignment assembly for at least one of said resonator mirrors comprising: i. a flexible hub member having a central aperture therethrough axially aligned with the gaseous medium, said hub member having a threaded outside surface; ii. means for mounting a resonator mirror to sealingly cover the central aperture of said hub member; iii. mirror adjustment and baseplates each having a threaded central aperture for screwed-on engagement with said threaded surface of said hub member so that said plates are parallel and spaced apart from each other, said mirror adjustment plate being situated nearest to said mirror; iv. said mirror adjustment plate having a plurality of bores located through the periphery thereof; and v. adjusting members extending through each of said peripherally-located bores to buttingly engage said baseplate for flexing said hub member to optically align and adjust said optical resonator mirrors.
Claim 2
Dependent Claim
183 words
A gas laser comprising: a. envelope means for enclosing the gaseous medium; b. means for exciting said gaseous laser medium to provide energy levels therein required for laser action; c. a pair of optical resonator mirrors; and d. a mirror support and alignment assembly for at least one of said resonator mirrors comprising: i. a flexible hub member having a central aperture therethrough axially aligned with the gaseous medium, said hub member having a threaded outside surface; ii. means for mounting a resonator mirror to sealingly cover the central aperture of said hub member; iii. mirror adjustment and baseplates each having a threaded central aperture for screwed-on engagement with said threaded surface of said hub member so that said plates are parallel and spaced apart from each other, said mirror adjustment plate being situated nearest to said mirror; iv. said mirror adjustment plate having a plurality of bores located through the periphery thereof; and v. adjusting members extending through each of said peripherally-located bores to buttingly engage said baseplate for flexing said hub member to optically align and adjust said optical resonator mirrors.
Claim 3
Dependent Claim
40 words
A laser as in claim 1 wherein said hub member forms an integral part of said envelope means, and wherein said mirror mounted to cover the central aperture of said hub member also forms a part of said envelope means.
Claim 4
Dependent Claim
60 words
A gas laser as in claim 1 wherein said hub member has a first threaded region upon which said baseplate is screwed, and a second region upon which said mirror adjustment plate is screwed, and wherein the diameter of the first threaded region and the central aperture of said baseplate are greater than the diameter of said second threaded region.
Claim 5
Dependent Claim
33 words
A gas laser as in claim 1 wherein said threaded outside surface comprises a single threaded region and the central apertures of said base and mirror adjustment plates are of the same diameter.
Claim 6
Dependent Claim
166 words
A gas laser comprising: a. envelope means for enclosing the gaseous medium; b. means for exciting said gaseous laser medium to provide energy levels therein required for laser action; c. a pair of optical resonator mirrors; and d. a mirror support and alignment assembly for at least one of said resonator mirrors comprising: i. a flexible hub member having a central aperture therethrough axially aligned with the gaseous medium, said hub member having a threaded outside surface; ii. means for mounting a resonator mirror to sealingly cover the central aperture of said hub member; iii. mirror adjustment and baseplates each having a threaded central aperture for screwed-on engagement with said threaded surface of said hub member so that said plates are parallel and spaced apart from each otHer, said mirror adjustment plate being situated nearest to said mirror; and iv. means for adjusting the position of said mirror adjustment plate relative to said baseplate by flexing said hub member to optically align said optical resonator mirrors.
Claim 7
Dependent Claim
166 words
A gas laser comprising: a. envelope means for enclosing the gaseous medium; b. means for exciting said gaseous laser medium to provide energy levels therein required for laser action; c. a pair of optical resonator mirrors; and d. a mirror support and alignment assembly for at least one of said resonator mirrors comprising: i. a flexible hub member having a central aperture therethrough axially aligned with the gaseous medium, said hub member having a threaded outside surface; ii. means for mounting a resonator mirror to sealingly cover the central aperture of said hub member; iii. mirror adjustment and baseplates each having a threaded central aperture for screwed-on engagement with said threaded surface of said hub member so that said plates are parallel and spaced apart from each otHer, said mirror adjustment plate being situated nearest to said mirror; and iv. means for adjusting the position of said mirror adjustment plate relative to said baseplate by flexing said hub member to optically align said optical resonator mirrors.
