Abstract
Abstract An adjustment device for adjusting the reflector mirrors of a laser resonator to be precisely parallel to one another comprises a carrier and an integral adjustment head together having an H-cross section provided by a recess system of a peripheral outer recess flanked by a pair of inner circular recesses so that an axially elastic and adequately side stable and temperature permanent adjustment derives.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
In a laser resonator of the type which includes a reflector mirror mounted in an adjustment head carrier and spaced from the carrier by an outer peripheral recess therebetween and in which the carrier and the adjustment head comprise a light passageway therethrough having an axis, and in which adjustment elements are carried by the adjustment head and engage the carrier, the improvement therein comprising: first means defining a first radially extending circular recess about the light passage in the carrier and a first thin discoid wall separating said first recess from the outer peripheral recess; and second means defining a second circular recess about the light passageway in the adjustment head and a second thin discoid wall separating said second recess from the outer peripheral recess.
Claim 2
Dependent Claim
127 words
In a laser resonator of the type which includes a reflector mirror mounted in an adjustment head carrier and spaced from the carrier by an outer peripheral recess therebetween and in which the carrier and the adjustment head comprise a light passageway therethrough having an axis, and in which adjustment elements are carried by the adjustment head and engage the carrier, the improvement therein comprising: first means defining a first radially extending circular recess about the light passage in the carrier and a first thin discoid wall separating said first recess from the outer peripheral recess; and second means defining a second circular recess about the light passageway in the adjustment head and a second thin discoid wall separating said second recess from the outer peripheral recess.
Claim 3
Dependent Claim
37 words
The improved laser resonator of claim 1, and further comprising: a third wall separating the outer peripheral recess from the light passageway, said first and second thin discoid walls and said third wall having the same thickness.
Claim 4
Dependent Claim
20 words
The improved laser resonator of claim 1, wherein: all of said recesses comprise the same width in the axial direction.
Claim 5
Dependent Claim
18 words
The improved laser resonator of claim 1, wherein: said first and second circular recesses comprise the same diameter.
Claim 6
Dependent Claim
27 words
The improved laser resonator of claim 4, wherein: said diameter of said first and second recesses is approximately equal to twice the diameter of the light passageway.
