Abstract
Abstract A gas transport laser has several discharge sections through which the laser gas flows and is attached on mounts. The mounts have borings for connection of the discharge tube sections, as well as for the intake and discharge in such a manner that the discharge tube sections, the gas supply and the gas discharge are parallel to each other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
In a gas transport laser system having a plurality of discharge sections through which laser gas flows and being attached on mounts, the improvement being in that said mounts have borings for connection of the discharge tube sections as well as for the laser gas intake and the laser gas discharge, said borings being located in said mounts in such a manner that said discharge tube sections and said gas supply and said gas discharge are parallel with one another, an electrode being in each of said mounts, said electrodes in adjacent mounts being of opposite polarity, said electrodes in the end most mounts being of the same polarity, said gas supply communicating with each of said mounts having their electrodes of the same polarity, said gas discharge communicating with the remaining intermediate mounts having their electrodes of opposite polarity to mounts communicating with said gas supply; and a laser mirror being attached to each one of said end most mounts which accommodate said discharge tube sections through which laser gas flows.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
59 words
Laser according to claim 1, characterized thereby that said mounts are L-shaped, a longitudinal boring being provided in each leg of said mounts, the center axes of said longitudinal borings being parallel to the attachment plane of its mount and at different distances from the attachment plane, and said longitudinal borings being interconnected by means of a lateral boring.
Claim 4
Dependent Claim
28 words
Laser according to claim 2, characterized thereby that said longitudinal borings have the same diameter, and various tube diameters can be accommodated by means of slip-on connector plates.
Claim 5
Dependent Claim
31 words
Laser according to one of claims 1 through 3, characterized thereby that a gas cooling unit can be accommodated in said longitudinal boring as well as in said gas discharge line.
Claim 6
Dependent Claim
26 words
Laser according to claim 4, characterized thereby that said system is a CO 2 gas transport, and said cooling unit being a gilled tube hose cooler.
