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