Abstract:
1. A laser device comprising: a plurality of linear resonator tubes for a gas to be excited, the plurality of linear resonator tubes being in fluidic communication with each other and forming a common tubular space; connecting elements arranged in corners between adjacent resonator tubes of the common tubular space and connecting adjacent resonator tubes; excitation means for the resonator tubes for exciting the gas in the resonator tubes for generating a laser light; mirrors arranged in the connecting elements for reflecting laser light between the resonator tubes; and a partially reflecting output coupler for coupling out a laser beam, wherein the resonator tubes, which are in fluidic communication with each other, are arranged in the shape of a helix, surrounding a central space free of resonator tubes, wherein the arrangement in the shape of the helix comprises a plurality of layers of resonator tubes on top of one another, wherein the plurality of layers of resonator tubes are interconnected to form one common gas volume.
