Abstract
The invention relates to a laser device comprising at least three linear laser gain volumes (12) for a gas to be excited, connecting elements (20) for connecting adjacent laser gain volumes, the laser gain volumes being mechanically coupled to other, and forming a common volumetric space, excitation means (50) for the laser gain volumes for exciting the gas in the laser gain volumes for generating a laser light, mirrors (22) arranged in the connecting elements for reflecting laser light between the laser gain volumes, a totally reflecting rear mirror (44), and a partially reflecting output coupler (42) for coupling out a laser beam. The laser gain volumes are arranged in the shape of an open or closed ring surrounding a free central space (8) between them. The invention also relates to a method for marking an object.
