Abstract
Abstract A gaseous laser having an internal optical resonator is provided with external stabilizing means for maintaining alignment of mirrors forming the optical resonator. Means are also provided for allowing expansion of the remainder of the gas-confining envelope relative to the stabilized resonator mirrors during the operation of the laser.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
185 words
A gaseous laser having an integral optIcal resonator comprising: a. an enclosure for confining the gaseous laser medium; b. means for exciting said gaseous laser medium to provide energy levels therein required for laser action; c. an optical resonator comprising a pair of axially aligned mirrors; d. means for securing said resonator mirrors to form an integral part of said gas-confining enclosure; e. mirror mounts for adjustably supporting said resonator mirrors, each of said mirror mounts comprising a pair of tubular members having unequal diameters; f. means external to said enclosure for providing support to and stabilizing said aligned optical resonator mirrors, and external means comprising a plurality of rods of a material having a low coefficient of thermal expansion extending between said optical resonator mirror supports; and g. means for allowing expansion of the remainder of said enclosure relative to said stabilized resonator mirrors, said expansion allowing means comprises a diaphragm connecting said pair of tubular members, wherein said resonator mirror is mounted to one of said pair of tubular members, and wherein the other of said tubular members is mounted to said enclosure.
