Abstract
Abstract A holder supporting a gas laser holder has two pair of leaf springs, each pair being situated in a plane at right angles to the longitudinal axis of the gas discharge laser and on either side of said laser, thereby isolating the laser device from bending moments as a result of temperature gradients in the laser or holder.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
93 words
A gas discharge laser device comprising a tubular gas discharge laser having a longitudinal axis, a holder, at least two pairs of bifurcated leaf springs connected to said holder, each pair of leaf springs being located in a plane substantially at right angles to the longitudinal direction of the gas discharge laser, and two clamping bands provided around the laser and attached to each of said leaf springs on either side of said laser through both bifurcations of each leaf spring, each band thereby forming an assembly with one pair of leaf springs.
Claim 2
Dependent Claim
93 words
A gas discharge laser device comprising a tubular gas discharge laser having a longitudinal axis, a holder, at least two pairs of bifurcated leaf springs connected to said holder, each pair of leaf springs being located in a plane substantially at right angles to the longitudinal direction of the gas discharge laser, and two clamping bands provided around the laser and attached to each of said leaf springs on either side of said laser through both bifurcations of each leaf spring, each band thereby forming an assembly with one pair of leaf springs.
Claim 3
Dependent Claim
36 words
A gas discharge laser device as claimed in claim 1, wherein the points of engagement of all the leaf springs to the holder are situated substantially in a plane including the longitudinal axis of the laser.
Claim 4
Dependent Claim
22 words
A gas discharge laser device as claimed in claim 1, wherein the leaf springs are welded to the holder by spot welding.
Claim 5
Dependent Claim
34 words
A gas discharge laser device as claimed in claim 3, wherein said holder is provided with lugs situated substantially in the planes of the pairs of leaf spring and welded to the leaf springs.
Claim 6
Dependent Claim
47 words
A gas discharge laser device as claimed in claim 4, wherein the holder comprises an elongated planar bottom plate provided with two lugs at each end, said lugs being bent substantially at right angles to the plane of the plate and spot welded to the leaf springs.
Claim 7
Dependent Claim
19 words
A gas discharge laser device as claimed in claim 5, wherein the bottom plate has a number of apertures.
Claim 8
Dependent Claim
30 words
A gas discharge laser device as claimed in claim 4, further comprising means situated near the lugs on the bottom plate for connecting the laser device to any given surface.
Claim 9
Dependent Claim
31 words
A gas discharge laser device as claimed in claim 7, wherein the bottom plate is slightly bent out of the plane through the connecting means substantially centrally between the two ends.
Claim 10
Dependent Claim
25 words
A gas discharge laser device as claimed in claim 7, wherein the bottom plate is slightly curved out of the plane through the connecting means.
Claim 11
Dependent Claim
19 words
A gas discharge laser device as claimed in claim 1, wherein the holder comprises a punched ribbon of metal.
