Abstract
Laser device comprising at least two gas laser units (10), stacked in layers, each laser unit comprising a plurality of resonator tubes (12), the resonator tubes being in fluidic communication with each other and forming a common tubular space, connecting elements (20, 21) for connecting adjacent resonator tubes so as to form a loop, mirrors (22) arranged in the connecting elements for reflecting the laser light between the resonator tubes, a rear mirror (44) and a partially reflecting output coupler (42) for coupling out a laser beam. In each laser unit an integrated output flange (40) comprises the rear mirror, the partially reflecting output coupler and an output mirror (46) which deflects the laser beam passing through the output coupler to a scanning device (80) located in the central space (8) surrounded by the resonator tubes. The invention also relates to a method for marking an object.
