Abstract
The invention relates to a marking apparatus for marking an object with laser light, which apparatus comprises at least one gas laser for emitting at least one laser beam for marking the object. The at least one gas laser comprises a plurality of resonator tubes (12) for receiving a laser gas, a plurality of heat dissipaters (20) for dissipating heat from the resonator tubes (12) is provided, each resonator tube (12) is thermally connected to one of the heat dissipaters (20), and each heat dissipater (20) comprises microchannels for receiving a cooling fluid.
