Abstract
Abstract A laser arrangement, and particularly a gas laser, has resonator means contained in a housing or enclosure and mounted therein by yieldable, vibration-dampening means in a manner to mechanically isolate the resonator with respect to the housing so that shifting or expansion of the housing during a warm-up period will not disturb or effect the dimensioning or spacing of reflectors forming a portion of the resonator means. Also, any misalignment of a gas laser tube relative to the resonator reflectors due to thermal expansion or otherwise is avoided by mounting the tube directly in the resonator and by not connecting the tube to the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A laser arrangement comprising a pair of optical reflector means, a structure for positioning said pair of optical reflector means in a predetermined position to form an optical resonator, said structure supporting a laser active element between said pair of optical reflector means, a housing means receiving said structure, and vibration dampening connector means for supporting said structure in the housing means, said connector means having a yieldable member for mechanically isolating said structure from said housing means so that the yieldable member prevents the transmission to said structure of vibrations which are applied to the housing means and prevents the application to said structure of stresses which are created in the housing means due to thermal expansion and contraction.
Claim 2
Dependent Claim
120 words
A laser arrangement comprising a pair of optical reflector means, a structure for positioning said pair of optical reflector means in a predetermined position to form an optical resonator, said structure supporting a laser active element between said pair of optical reflector means, a housing means receiving said structure, and vibration dampening connector means for supporting said structure in the housing means, said connector means having a yieldable member for mechanically isolating said structure from said housing means so that the yieldable member prevents the transmission to said structure of vibrations which are applied to the housing means and prevents the application to said structure of stresses which are created in the housing means due to thermal expansion and contraction.
Claim 3
Dependent Claim
94 words
A laser arrangement according to claim 1 wherein the laser active element is a gas laser tube, and wherein said structure includes a plurality of substantially parallel rods forming an open cage work, said rods being held in their respective opposite ends by a pair of end plates, said gas laser tube being positioned in said cage work generally parallel to said rods, and said pair of optical reflector means of the optical resonator being supported by the pair of end plates in a plane perpendicular to the axis of said gas laser tube.
Claim 4
Dependent Claim
48 words
A laser arrangement according to claim 2 wherein said cage work includes a pair of tube mounting plates extending generally transversely between said rods and spaced between said pair of end plates, said gas laser tube passing through apertures formed in the mounting plates and being supported thereby.
Claim 5
Dependent Claim
55 words
A laser arrangement according to claim 1 wherein said connector means each include an elastic, resilient core forming said yieldable member and a pair of rigid plate members affixed at opposite ends of said core, said rigid plate members forming mounting portions for attachment of said connector means between said housing means and said structure.
Claim 6
Dependent Claim
18 words
A laser arrangement according to claim 4 wherein said elastic core consists essentially of a resilient rubber material.
