Abstract
The invention refers to a laser device comprising a plurality of linear resonator tubes (12) for a gas to be excited, the resonator tubes being in fluidic communication with each other and forming a common tubular space, connecting elements (20) arranged in corners between adjacent resonator tubes of a common tubular space, excitation means (50) for the resonator tubes for exciting the gas in the resonator tubes for generating a laser light, mirrors (22) arranged in the connecting elements for reflecting laser light between the resonator tubes, and a partially reflecting output coupler (42) for coupling out a laser beam. The resonator tubes are arranged in the shape of a helix, surrounding a free central space. The invention also relates to a method for generating laser light with such a laser device.
